Patch to fix "cannot find -lgcc_eh" error message

I tried to cross-compile glibc 2.13 + MIPS port with GCC 4.6.0 and:

echo "libc_cv_forced_unwind=yes" > config.cache
echo "libc_cv_c_cleanup=yes" >> config.cache
BUILD_CC="gcc" \
    CC="mips64el-unknown-linux-gnu-gcc -march=loongson2f -mabi=n32" \
    AR="mips64el-unknown-linux-gnu-ar" \
    RANLIB="mips64el-unknown-linux-gnu-ranlib" \
    /microcebus/build/glibc-2.13/configure \
    --prefix=/usr \
    --libexecdir=/usr/lib/glibc \
    --build=mipsel-cross-linux-gnu \
    --host=mips64el-unknown-linux-gnu \
    --disable-profile \
    --enable-add-ons \
    --with-tls \
    --enable-kernel=2.6.26 \
    --with-__thread \
    --with-binutils=/microcebus/cross-tools/bin \
    --with-headers=/microcebus/usr/include \
    --cache-file=config.cache
make

make gives me the following error message:
