There's another cyclic issue: at least as of glib-2.22.5, glib
./configure requires pkg-config to exist. It's easy to pass flags to
avoid actually needing it (either overriding with specific flags for
whatever external deps and/or disabling the use of them altogether),
but even still:

checking for _FILE_OFFSET_BITS value needed for large files... no
checking for pkg-config... no
configure: error: *** pkg-config not found. See http://www.freedesktop.org/software/pkgconfig/

That's a problem if glib2 has to be built first as an external dep of
pkg-config or as an internal bundled part of the pkg-config suite.
