Re: [libvirt] [PATCH] Update LIBVIRT_CHECK_LIB and LIBVIRT_CHECK_LIB_ALT to use pkg-config

For example on FreeBSD the "yajl" library is located at "/usr/local/lib" and it's not in default LIBS and therefore the configure fails that "yajl" not installed. We can use the "PKG_CHECK_MODULES" to get the correct library path in case the library provides pkg-config file definition, otherwise the old approach is used.
