Fails to build on mips and mipsel machines

[Sjoerd Simons <sjoerd@…>]

Hi,

On mips and mipsel the gcc -pthread switch doesn't link in the pthreads lib when building a shared library. See for example the output of a mips build of avahi:

http://buildd.debian.org/fetch.php?&pkg=avahi&ver=0.6.4-1&arch=mips&stamp=1137509680&file=log&as=raw

For more information see the discussion at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=273671

This can be fixed by having acx_pthread do some extra checking. Patch attached..

Do some extra checking at configure time for the pthread flags

I guess it makes sense to file a bug on Debian's "autoconf-archive" package, too, since our acx_pthread.m4 is a 1:1 copy of their script.

I will merge this now, anyway.

Applied in r1101, thank you!

The patch was undone in svn revision 1160.. I'll send the patch to the automake archive too, so this hopefully won't happen again :)
