unreliable HAVE_PTHREAD_TIMEDJOIN_NP check about gearmand

[esabol]

Some web pages with potentially useful information that I came across:

http://stackoverflow.com/questions/11551188/alternative-to-pthread-timedjoin-np

How another project fixed a similar issue:

Thank you @esabol. First link leads me to pthread.map. At least pthread_timedjoin_np is mentioned there.

It appears as though, on some FreeBSD versions, you need to link with -lthr to use pthread_timedjoin_np?

Seeing as Travis CI isn't isn't likely to have FreeBSD support soon: travis-ci/travis-ci#1818 , this is blocked on having another CI platform to test on. As luck would have it, my day job is building one such system with support for user defined images. But that may never leave beta, so another option would be to have somebody run a FreeBSD buildbot/jenkins/etc. and report results via the Github API's.

Unfortunately it doesn't work. I'm using FreeBSD 11.

CXX=c++49 CC=gcc LIBS="-lthr" ./configure --disable-option-checkin --with-postgresql=no --enable-shared=no
gmake

throws exception:
libgearman-server/gearmand_thread.cc: In function 'void gearmand_thread_free(gearmand_thread_st*)': libgearman-server/gearmand_thread.cc:295:68: error: 'pthread_timedjoin_np' was not declared in this scope pthread_error= pthread_timedjoin_np(thread->id, NULL, &ts);

The line 295 lies in #if defined(HAVE_PTHREAD_TIMEDJOIN_NP) && HAVE_PTHREAD_TIMEDJOIN_NP block.

I'm trying to build gearmand on my local FreeBSD host. If it success I'll contact FreeBSD gearmand maintainer. But there are some other issues to do yet.
