我正在遵循LFS指南7.2，我在5.7节。执行Glibc make时，我收到以下错误。
-o /mnt/lfs/sources/glibc-build/math/s_isnan.os -MD -MP -MF /mnt/lfs/sources/glibc-build/math/s_isnan.os.dt -MT /mnt/lfs/sources/glibc-build/math/s_isnan.os
../sysdeps/ieee754/dbl-64/wordsize-64/s_isnan.c:30:1: error: '__EI___isnan' aliased to external symbol '__GI___isnan'
make[2]: *** [/mnt/lfs/sources/glibc-build/math/s_isnan.os] Error 1

make[1]: *** [math/subdir_lib] Error 2
make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.16.0'

我的GCC版本是4.7.2。我应采取哪些步骤来纠正此错误？
