powerpc-tunes: Introduce bigendian tune
PATCH 1/4 powerpc-tunes: Introduce bigendian tune
This helps in defining LE tunes and at the same time specifies endianness on compiler cmdline clearly, clang e.g. defaults to little-endian always, so unless specified with -mbig-endian won't compile the code right

PATCH 3/4 gcc: Move STANDARD_STARTFILE_PREFIX_1 and STANDARD_STARTFILE_PREFIX_2 back to gcc.c
In reply to Khem Rajwhen compiling for ppc64, build emits additional STANDARD_STARTFILE_PREFIX_1 and STANDARD_STARTFILE_PREFIX_2 into gcc/defaults.h which is not conditional because it really want to override others with this new value, but it ends up with two definitions since it gets emitted _after_ the definition this patch moves to default.h and ends up in duplicate defines.
