Mudflap was removed in GCC 4.9, and libiberty.a is apparently no longer
installed.

The mudflap run time checker was removed in GCC 4.9 and it is superseded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

These take a rather long time.

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

The "unary operator expected" error seems to be caused by this line
(libgcc/Makefile.in:291):
MULTIOSSUBDIR := $(shell if test $(MULTIOSDIR) != .; then echo /$(MULTIOSDIR); fi)

gcc_gxx_include_dir loses its preceding slash if a non-null sysroot is set.

The GCC Internals manual (gcc/doc/fragments.texi) says:

> MULTILIB_OSDIRNAMES also encodes the multiarch name, thus subsuming

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.

This should add /usr/include/<target> to the include search list.

For some reason, the --with-boot-ldflags option causes NEEDED references to
libstdc++.so.6 and libgcc_s.so.1 to be added to the DYNAMIC sections of gcc,
cpp, cc1, etc.
These options are only useful during the first stage of the bootstrap of the
first ProteanOS port, anyway, and they aren't strictly necessary even then.

This is necessary for cross compilers, at least.

It's a development file, not a critical system file.
