This isn't a bug in m4 or anything architecture-specific, it's a regression
that was introduced by an upstream change in glibc [1] and mainly affects
qemu-user which we are using for m68k and sh4 [2].
While the change in glibc is most certainly correct (I don't have enough
background knowledge to comment on that), it broke qemu-user for everyone
and so far there is no possible fix in sight.
I am CC'ing this to libc-alpha in the hope that someone from glibc upstream
might give us a tip on how to resolve the issue. Not being able to use qemu-user
anymore is quite a deal breaker because lots of people use qemu-user for
debugging issues on foreign architectures which is now no longer possible.
Thanks,
Adrian
