Hi!

Running automated tests again, I found that targeted for s390x-linux-gnu (1a87f8381085de50726634e8cb4a651c05b272b5) won't build:


../gcc/configure --target=s390x-linux-gnu --enable-werror-always --enable-languages=all --disable-gcov --disable-shared --disable-threads --without-headers --prefix=/var/lib/laminar/run/gcc-s390x-linux-gnu/1/toolchain-install
[...]

make all-gcc
