Write a (non-working) cortexa8 TBB setup.

EGLIBC fails to build:
  ../sysdeps/unix/syscall.S: Assembler messages:
  ../sysdeps/unix/syscall.S:28: Error: cannot represent SWI relocation in this object file format
  make[2]: *** [/home/pj/bbl/sys.cortexa8/fsmnt/src/eglibc-build/misc/syscall.o] Error 1

  make[1]: Leaving directory `/home/pj/bbl/sys.cortexa8/fsmnt/src/eglibc-2.15/libc'
  make: *** [all] Error 2

Apparently SWI (software interrupt) vector table relocation is only
available in certain ARM cores (including Cortex-A8).

+ABOUT THIS GUIDE
+================
+
+This is a guide to building a custom BusyBox/Linux-libre system with the GNU
+toolchain.  It mostly follows Cross Linux From Scratch Sysroot version
+SVN-0.0.1-20090726-x86, except that it uses more recent versions of software
+packages and uses a BusyBox-based userspace rather than a GNU-based one.  This
+guide assumes the use of a GNU/Linux host system with all the necessary
+development software (GCC, GNU Binutils, Subversion, etc.) already installed.
+
+This version of the procedure is designed to build a bootstrap builder system
+capable of cross-compiling software for an ARM Cortex-A8 core.
+
+It is recommended that you read Cross Linux From Scratch Sysroot version
+SVN-0.0.1-20090726-x86 to understand the full build process and the rationale
+behind various elements of the setup.

+
+PROCEDURE
+=========
+
+Make a directory in which all work will be done.  Under this directory, make
+directories 'src' and sys.cortexa8':
+  $ mkdir src sys.cortexa8
+
+Download all of the necessary source archives and branches.
+  $ cd src
+  $ wget http://www.busybox.net/downloads/busybox-1.19.3.tar.bz2
+  $ wget http://www.fsfla.org/svnwiki/selibre/linux-libre/download/releases/\
+  > 3.2.10-libre/linux-3.2.10-libre.tar.bz2
+  $ svn co svn://svn.eglibc.org/branches/eglibc-2_15 eglibc-2.15
+  $ wget http://ftp.gnu.org/gnu/gcc/gcc-4.6.2/gcc-4.6.2.tar.bz2
+  $ wget http://ftp.gnu.org/gnu/binutils/binutils-2.22.tar.bz2
+  $ wget http://ftp.gnu.org/gnu/make/make-3.82.tar.bz2
+  $ wget ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2
+  $ wget http://www.mpfr.org/mpfr-current/mpfr-3.1.0.tar.bz2
+  $ wget http://www.multiprecision.org/mpc/download/mpc-0.9.tar.gz
+  $ for file in *.tar.bz2; do tar -xjf ${file}; done
+  $ for file in *.tar.gz; do tar -xzf ${file}; done
+  $ cd ..
+
+Make and mount the filesystem.  mkfs and mount must be run as the superuser, but
+dd shouldn't need to be.
+  $ cd sys.cortexa8
+  $ dd if=/dev/zero of=fs bs=1024 count=$((3*1024*1024))
+  # mkfs -t ext4 fs
+  $ mkdir fsmnt
+  # mount -o loop fs fsmnt
+
+Set up a new user.
+  # groupadd tbb-cortexa8
+  # useradd -s /bin/bash -g tbb-cortexa8 -d /home/tbb-cortexa8 tbb-cortexa8
+  # mkdir -pv /home/tbb-cortexa8
+  # chown -v tbb-cortexa8:tbb-cortexa8 /home/tbb-cortexa8
+  # passwd tbb-cortexa8
+  # chown -Rv tbb-cortexa8:tbb-cortexa8 fsmnt
+
+Set up the toolchain work environment.  Be sure to change '<BASE_DIR>' to the
+absolute path to the base work directory you made earlier, and adjust the
+configuration name in BBL_TARGET if you're building for a different
+architecture.  We're using GNU Bash as the new user's default shell for
+convenience; this has no effect on the target system.
+  $ su - tbb-cortexa8
+  $ cat > ~/.bash_profile <<EOF
+  > exec env -i HOME="${HOME}" TERM="${TERM}" /bin/bash
+  > EOF
+  $ cat > ~/.bashrc <<EOF
+  > set +h

+  $ source ~/.bash_profile
+
+Make system directories.  These commands should give you a system that is
+compliant with Filesystem Hierarchy Standard version 2.3.  Note that the range
+syntax in many of these command lines is a non-standard feature of GNU Bash;
+this may not work on other shells.
+  $ mkdir -pv ${BBL}/{bin,boot,dev,etc/opt,home,lib,media,mnt,opt,proc}
+  $ install -dv -m 0750 ${BBL}/root
+  $ mkdir -pv ${BBL}/{sbin,srv,sys}
+  $ install -dv -m 1777 ${BBL}{,/var}/tmp
+  $ mkdir -pv ${BBL}/usr/{,local/}{bin,include,lib,sbin,share/{man,misc},src}
+  $ mkdir -pv ${BBL}/usr/local/{etc,games}
+  $ mkdir -pv ${BBL}/usr/{,local/}share/{doc,info,locale,terminfo,zoneinfo}
+  $ mkdir -pv ${BBL}/usr/{,local/}share/man/man{1,2,3,4,5,6,7,8}
+  $ ln -sv share/man ${BBL}/usr/local/man
+  $ mkdir -pv ${BBL}/var/{cache,lib/misc,local,lock,log,mail,opt,run,spool}
+
+Write the passwd and group files.

+
+If CONFIG_FEATURE_UTMP and/or CONFIG_FEATURE_WTMP are enabled in BusyBox,
+certain BusyBox applets (getty, login, init, etc.) will log user logins to
+/var/run/utmp and/or /var/run/wtmp.  However, BusyBox's supporting library won't
+create /var/run/wtmp if it doesn't exist.  So create these files now and set
+proper modes for them.
+  $ touch ${BBL}/var/run/{u,w}tmp
+  $ chmod -v 664 ${BBL}/var/run/{u,w}tmp
+/var/run/utmp is used to track logged-in users.  /var/run/wtmp is used to record
+when users log into and out of the system.  NB: This is an odd location for
+wtmp, but that's where an unpatched BusyBox will expect it.
+
+Make and change to a directory for package source code.
+  $ mkdir -v ${BBL}/src
+  $ cd ${BBL}/src
+
+At this point and after every milestone (maybe after each package installation),
+I recommend you create a snapshot of the filesystem.  To do so, first exit the
+shell environment of user 'tbb-cortexa8'.
+  $ exit
+As the superuser, unmount the filesystem.
+  # umount fs
+Make a copy of the filesystem.  Replace '<UNIQUE_NAME>' with something to
+identify the milestone (for example, at this point I named my snapshot image
+'fs.01-fs-hier' to note that it was the first snapshot and that I just finished
+making the filesystem hierarchy).
+  $ cp -p fs fs.<UNIQUE_NAME>
+As the superuser, mount the filesystem again.
+  # mount -o loop fs fsmnt
+Log in as user 'tbb-cortexa8' and return to the src directory in the filesystem.
+  $ su - tbb-cortexa8
+  $ cd ${BBL}/src
+Now, if something goes wrong, you can revert to a previous filesystem image by
+going through this section and swapping the arguments to 'cp'.
+
