求救：关于GCC编译问题

我升级过glibc，升级成功后用GCC编译任何C文件都得到这样的错误：
/usr/lib/gcc/i486-slackware-linux/3.4.6/../../../../i486-slackware-linux/bin/ld:/usr/lib/gcc/i486-slackware-linux/3.4.6/../../../libc.so: file format not recognized; treating as linker script
/usr/lib/gcc/i486-slackware-linux/3.4.6/../../../../i486-slackware-linux/bin/ld:/usr/lib/gcc/i486-slackware-linux/3.4.6/../../../libc.so:5: syntax error
collect2: ld returned 1 exit status


请教高手们怎么解决啊？？急
