Mostly offset changes. libmudflap is gone, there's a bit of fuzz in
gcc/Makefile.in, and the indentation in the added gcc/gcc.c code is now
more GNU-Coding-Standards-conformant.

The mudflap run time checker was removed in GCC 4.9 and it is superseded
by Address Sanitizer.

This was causing errors due to an unquoted argument to the test utility:

Apparently, some indentation changed between versions 4.7.2 and 4.7.3 of GCC.
BusyBox patch "does not use the location information, but instead treats a hunk
as a sort of regex" (BusyBox 1.21.0 editors/patch.c:209). It ignores line
numbers and relies on context matching to find hunks to patch. Therefore,
changes to the context in the original file cause BusyBox patch to fail to apply
a hunk. Fuzz is fatal.
A patch needs to be refreshed when a new upstream version modifies its context.

GNU Patch can handle spaces between file names and dates, but BusyBox patch
requires tabs.

The GCC Internals manual (gcc/doc/fragments.texi) says:
> For configurations that support both multilib and multiarch,
> MULTILIB_OSDIRNAMES also encodes the multiarch name, thus subsuming
> MULTIARCH_DIRNAME.
>
[...]
>
> MULTIARCH_DIRNAME is not used for configurations that support both multilib
> and multiarch. In that case, multiarch names are encoded in
> MULTILIB_OSDIRNAMES instead.
This sounds like the makefile macro used depends on the build-time user
configuration; that is, the options --disable-multilib and --enable-multiarch
should cause MULTIARCH_DIRNAME to be used.
Instead, it seems MULTILIB_OSDIRNAMES is used, even if multilib is disabled. So
apparently, "configurations that support both" means GCC target configurations
that support both features, not build-time user configurations that enable them.
