I build GCC with -mcmodel=extreme in BOOT_CFLAGS, but I haven't 
reproduced the problem you mentioned.

$../configure --host=loongarch64-linux-gnu 
--target=loongarch64-linux-gnu --build=loongarch64-linux-gnu \

         --with-arch=loongarch64 --with-abi=lp64d --enable-tls 
--enable-languages=c,c++,fortran,lto --enable-plugin \

         --disable-multilib --disable-host-shared --enable-bootstrap 
--enable-checking=release

     $ make BOOT_FLAGS="-mcmodel=extreme"

What did I do wrong?:-(
