This fixes the error

 make[3]: *** [libgcc2.a] Error 1

 make[3]: Leaving directory `/build/arm-unknown-linux-gnu/gcc-2.95.3-glibc-2.2.2/build-gcc-core/gcc'

 in what I think is a nicer way than the patch used by the arm team,

 i.e. "perl -pi -e 's/^(TARGET_LIBGCC2_CFLAGS.*)/$1 -Dinhibit_libc -D__gthr_posix_h/' gcc/config/arm/t-linux"

 which seems a bit of a kludge.
