帮助,在安装glibc-2.3.2时，configure 出错（redhat9, p2 233）

glame

../glibc-2.3.2/configure --prefix=/tools \
    --disable-profile --enable-add-ons \
    --with-headers=/tools/include \
    --with-binutils=/tools/bin \
    --without-gd
后，出错如下：
running configure fragment for ../glibc-2.3.2/sysdeps/i386/elf
running configure fragment for ../glibc-2.3.2/sysdeps/unix/sysv/linux
checking for egrep... (cached) grep -E
checking installed Linux kernel header files... 2.0.10 or later
*** On GNU/Linux systems it is normal to compile GNU libc with the
*** `linuxthreads' add-on.  Without that, the library will be
*** incompatible with normal GNU/Linux systems.
*** If you really mean to not use this add-on, run configure again
*** using the extra parameter `--disable-sanity-checks'.

明明是有--enable-add-ons 啊，为什么还有这个错误呢?
不管三七二十一，先加上`--disable-sanity-checks'，configure 通过，可是
在make的时候，出现error,错误如下：
gcc -B/tools/bin/ ../sysdeps/unix/sysv/linux/i386/system.c -c -std=gnu99 -O2 -Wo

请问是什么原因呢？
