GCC compiles the xgcc cross compiler and will compile target
libraries e.g. libstdc++. It uses autoconf to configure the target
libraries which uses /usr/bin/cpp to determine the presence of
host includes.
By using xgcc we will not risk to include /usr/include to find standard
headers. If we do our cross compile check will hit.
The gcc 3.4 series patch only addresses target-libstdc++ where the
gcc3.3 and gcc4 series patch all targets

Cleanup some errors in packaging when certain files do not exist.
Add GCOV_PREFIX* cross-profiling patches.
Pass in GFORTRAN_FOR_TARGET for cross builds.

Hack to make me rich and famous. Patch versions 3.4.4,
4.0.0, 4.0.2, 4.1.0, 4.1.0-snapshot, 4.2-snapshot and
activate the hack when cross compiling.
gcc will abort if you call it with -I/usr/include or
-I/opt/include or -I/sw/include.
Apply the patch when fail-fast is in the OVERRIDES

HACK to workaround an issue in using gcc -E as cpp for the
cross compiler for libmudflap, libstdc++ and other libs.
AC_CHECK_HEADERS will think it can use host headers, we simply
hack around this for now

Apply uclibc patches from the uclibc buildroot. All these
patches are guarded with #ifdefs and should not effect
other configurations.
