re PR middle-end/41260 (major regressions on *-apple-darwin10 at -m64 caused by r147995)
PR middle-end/41260
* gcc/config.gcc: Use darwin9.h and darwin10.h on darwin10 and later.
* gcc/config/darwin10.h: Add file to pass -no_compact_unwind on
LIB_SPEC for darwin10 and later since it always uses the unwinder in
libSystem which is derived from the gcc 4.2.1 unwinder.
