Eglibc cannot compile suffix of object files while trying to cross compile


When trying to configure the 32-bit version of eglibc, using the options:
Code:
BUILD_CC="gcc" CC="${CLFS_TARGET}-gcc ${BUILD32}" \
>     AR="${CLFS_TARGET}-ar" RANLIB="${CLFS_TARGET}-ranlib" \
>     CFLAGS="-march=$(cut -d- -f1 <<< $CLFS_TARGET32) -mtune=generic -g -O2" \
>     ../eglibc-2.15/configure --prefix=/tools \
>     --host=${CLFS_TARGET32} --build=${CLFS_HOST} \
>     --disable-profile --enable-add-ons \
>     --with-tls --enable-kernel=2.6.0 --with-__thread \
>     --with-binutils=/cross-tools/bin --with-headers=/tools/include \
>     --cache-file=config.cache
I get the following output:

Code:

checking for i686-pc-linux-gnu-gcc... x86_64-unknown-linux-gnu-gcc -m32

Trying to compile with the CC parameter set to just "gcc $BUILD32" gets me much further, although it does complain about the loss of a triplet. Doing so, however, gives me an error suggesting that:

Code:
checking for __builtin_expect... no
configure: error: support for __builtin_expect needed
I'm lost at this point. Can anyone offer any pointers?

Thanks,
