linux下编译交叉工具链的工具源码

# Taken from http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config.gcc.diff?r1=1.3&r2=1.4
# Should fix error
#   Configuration powerpc-host_apple-darwin7.3.0 not supported
# when configuring gcc-2.95 on Mac OS X for i686 target
# Also create xm-darwin.h, seems to be required, else we get the error
#   In file included from .../gcc-2.95.3/gcc/gencheck.c:21:
#   hconfig.h:11:30: rs6000/xm-darwin.h: No such file or directory
#   make[1]: *** [gencheck.o] Error 1
