Right.  I haven't tried building anything with SELinux disabled yet.

Arch does not enable SELinux support in GLib, so we can look at how they
tackled the issues that arise.

The reason I started looking at this was because I want to remove
propagated inputs that are in "Requires.private" in the pkg-config
files, as they should only be necessary when linking statically.

Unfortunately libselinux can only be built statically (AFAICT), so I
suspect most GLib dependents end up embedding libselinux.a, which I did
not account for in the initial size calculation.  :-)

(libselinux also fails to cross-compile, but then so does GLib)
