[Buildroot] [PATCH] libpjsip: disable parallel build

[Luca Ceresoli]

The libpjsip package has build issues on the autobuilders that look
like parallel build issues. These issues seem to be extremely hard to
reproduce, so let's disable parallel build and see if this fixes the
issue.

The suspect error message is:
  ...-ld: cannot find -lpjsua
  collect2: error: ld returned 1 exit status

Some of the failures:

No, this is _not_ the fix that I would like to see. But I'm still
unable to reproduce despite having attempted several builds, so this
is the best I could come up with... :-|

I also hate to apply such patches without really knowing what's going
on. But I've applied it nonetheless, so that we can see if it actually
solves the problem or not. If it does, then we can think of a better
solution, or at least reporting the build issue upstreaming to the
pjsip developers.

So, applied to master! Please monitor the autobuilders in the next
hours/days to see if the issue is resolved or not.

Best regards,

Thomas

I'm doing it almost daily since weeks now, why should I stop? ;)

Thanks for having applied it.

It's 15 days since this patch has been applied, and we had no more
autobuild failures on libpjsip-2.4.5 after that.

The time frame between the previous patch to libpjsip (9db9a6d2b3c595)
and this one lasted ~45 days and produced 13 autobuild failures.

I'm starting being moderately optimistic about having solved the
problem. I'll wait a few more days, then unless we see new failures I'll
report to the upstream mailing list.

Yes, I also haven't seen any libpjsip failure since quite some time.

I agree that disabling parallel build seems to have fixed the problem,
so you can report the issue upstream.

Thanks!
