ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.
       You probably need to set PKG_CONFIG_LIBDIR

Hasn't worked since 977a82ab; Paolo filed a bug against Clang -- it was
discussed here:
https://lists.nongnu.org/archive/html/qemu-devel/2016-02/msg02482.html
and filed here: https://bugzilla.redhat.com/show_bug.cgi?id=1306455


In the meantime, though, I haven't been able to use Clang on Fedora with
QEMU this month, and it reveals other interesting features of our
makefile like the one I was kvetching about here. :)
