[Qemu-devel] [PATCH v2 01/13] build-sys: fix qemu-ga -pthread linking

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

When linking qemu-ga under some configuration (when gthread-2.0.pc
doesn't have -pthread, as happening atm with meson build), you may
have this linking issue:

/usr/bin/ld: libqemuutil.a(qemu-thread-posix.o): undefined reference to symbol 'pthread_setname_np@@GLIBC_2.12'
/usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line

Make sure qemu-ga links with the pthread library, by adding correct
flags to libs_qga.
