Well, but if it's in the end a feature that no one is using and a test that isn't even part
of the upstream tests I don't see the point in testing it.

I'm just quoting jrtc27 from IRC. I'm not really an expert on that matter.

It seems that these two tests are currently the only tests that are not being ignored
that are failing unless I'm missing something (I just looked at the build log).
As for m68k and sh4, I currently can't enable the builds there as the fixes by
Adhemerval Zanella to unbreak glibc >= 2.28 on qemu-user have not been merged
yet anywhere (neither in Debian nor upstream).
I know that Adhemerval is testing glibc on my SH-7785LCR board regularly and I know
that Andreas Schwab is testing internally at SUSE on m68k (his openSUSE port for
m68k is unfortunately not public).
