backport-config.gcc-1.92.patch

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=1.91&r2=1.92
# Should fix error
#   Configuration x86_64-host_unknown-linux-gnu not supported
# when configuring gcc-2.95 on x86_64 build for i686 target
# It's a bit silly, since tm_file refers to files that don't exist,
# but as long as x86_64 is just the build machine, that doesn't matter.
