glibc-2.3.5-allow-gcc4-symbols.patch

linux下编译交叉工具链的工具源码

If I'm really lucky, this fixes the following error building with gcc-4.0.0:

../sysdeps/ieee754/dbl-64/s_isinf.c:29: error: 'isinf' aliased to undefined symbol '__isinf'
make[2]: *** [/home/dank/queue/jobdir.fast/crosstool-0.32/build/i686-unknown-linux-gnu/gcc-4.0.0-20050410-glibc-2.3.4/build-glibc/math/s_isinf.os] Error 1
make[1]: *** [math/subdir_lib] Error 2
make: *** [lib] Error 2
