[Bug bootstrap/20985] New: building mips/64 cross compiler on x86 produces incorrect assembler code for _divdi3 with -fnon-call-exceptions

./configure --enable-languages=c --disable-nls --disable-threads
--disable-shared --disable-checking --prefix=/usr --target=mips-linux
make TARGET_LIBGCC2_CFLAGS='-Dinhibit_libc -D__gthr_posix_h'

results in ...

(removing the '-.' in that line *G* makes it work with gas 2.15.94.0.2.2)
