In the last internal glib update, the glib configure script changed the
OSX framework flags from the form of "-framework Foo" to
"-Wl,framework,Foo". Unfortunately, libtool only understands the prior
form and doesn't include the appropriate -framework flags in the
libglib-2.0.la file. This ultimately causes pkg-config to fail to link
properly:
Undefined symbols for architecture x86_64:

Upstream has fixed this by including the new style -framework flags in
the glib-2.0.pc file. We can't use that here as we're bootstrapping
pkg-config itself. Rather than work around this with an OSX platform
check in pkg-config's configure, carry a downstream patch to revert
glib's configure to using the old format.
