build: rely on gnulib's pthread module Gnulib can guarantee that pthread.h exists, but for now, it is a dummy header with no support for most pthread_* functions. Modify our use of pthread to use function checks, rather than header checks, to determine how much pthread support is present. * bootstrap.conf (gnulib_modules): Add pthread. * configure.ac: Drop all pthread.h checks. Optimize function checks. Add check for pthread functions. * src/Makefile.am (libvirt_lxc_LDADD): Ensure proper link. * src/remote/remote_driver.c (remoteIOEventLoop): Depend on pthread_sigmask, now that gnulib guarantees pthread.h. * src/util/util.c (virFork): Likewise. * src/util/threads.c (threads-pthread.c): Depend on pthread_mutexattr_init, as a witness of full pthread support. * src/util/threads.h (threads-pthread.h): Likewise. 2010-04-29 02:39:11 +00:00			`* Copyright (C) 2009-2010 Red Hat, Inc.`
