My main concern is really whether --disable-64-bit-bfd still works.
I don't know if people still use this, but as long as it exists it seems
like it should continue to work. If RISC-V works in this setup, then it
is totally fine by me for gdb to follow, assuming it works as well.

Maybe to really test it has to be a 32 bit build with
--disable-64-bit-bfd and --enable-targets=all.
