Normally I would agree, but we are very near the freeze, so the time
required to properly investigate the issue might well be longer than
what is available to get to stretch, and thus stretch would release
without being able to cross-build a core component to nios2 (and
possibly other architectures). AFAIK, the fact that the real binary is
in .libs/$program is an internal implementation detail of libtool and
not a guaranteed interface, so it may well be possible (although
unlikely) that different architectures differ in behavior. Given that
the workaround in question lived for a relatively long time in
unstable and caused no issues, I think the case for reverting is
sound.

This of course assumes that it is relevant to reach stretch with the
cross-buildable component. If it is not, then I think investigating
the root cause will be more fruitful.

Indeed.
