linux编译glibc，一直报错

make版本号 GNU Make 3.81
gcc版本号 gcc version 4.4.2 20091027 (Red Hat 4.4.2-7) (GCC)
glibc版本号 #define RELEASE "stable"
#define VERSION "2.11.1"
kernal版本号 2.6.31.5-127.fc12.i686.PAE

源码unpack到 /usr/local/src/glibc-2.11.1
创建对象文件 ../glibc-2.11.1/configure --prefix=/usr
出现这个提示：config.status: creating config.make
config.status: creating Makefile
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing default commands
然后编译的时候出现这个错误：
make[2]: *** [/usr/local/src/glibc-build/math /s_frexp.os] Error 1
make[2]: Leaving directory `/usr/local/src/glibc-2.11.1/math'
make[1]: *** [math/subdir_lib] Error 2
