A solution was suggested by Rich Felker in the bug report. My plan is
to work on implementing this solution, but I was hoping to fix bug
#7250 first, which also affects the toolchain.

Not yet.

The patch I submitted was only for gcc 4.8.x, but I've since then
written patches for gcc 4.7, 4.8 and 4.9, I only lack the same patch
for the ARC special version. I'll work on this, but probably not this
week, since I'm taking care of merging patches this week.

I don't know. I don't know SuperH stuff, and it builds a multilib
toolchain by default, causing some issues. Needs investigation/thoughts
to see what could be the solution. Problem is that I don't personally
care much about SuperH, and we don't have a lot of contributors/users
using this architecture, so it reduces quite a bit the incentive to
work on such issues.

I agree with the solution.

These ones are mainly here to remind the respective architecture
maintainers that they should do something about these packages: we have
temporarily solve the situation by excluding those packages using
"depends on !<problematic architecture>", but ultimately there's no
technical reason for those packages to be disabled on those
architectures. So to not forget, I submitted those bug reports instead.
Here the intent is to distinguish packages that for some technical
reason do not support a given architecture (such as webkit, or jamvm,
that really do have some architecture-specific code) from packages
currently broken on a given architecture, but which could potentially
work.

That being said, while I'm pretty sure the dmraid issue on ARC will be
solved at some point, I have less hopes for the elfutils on Blackfin
and gpsd on Microblaze issues, since we don't receive much help to
maintain those two architectures in Buildroot...

Patches already sent. People were a little bit worried about the
consequences of the patches, but I don't think there's any other
solution, so I'd appreciate some review on the patches.

Yeah, I remember this issue, it was debugged on IRC, and the bug report
is a reminder to do some work to fix it properly.

Thanks,

Thomas
