Subject: [PATCH 1/3] setupext: respect $PKG_CONFIG

When cross-compiling, it is common to set the PKG_CONFIG env var to a
custom pkg-config that knows about the target.  Make sure we respect
that just like the standard pkg-config tools suggest (pkg.m4).  If it
isn't set, we use the same default as today -- "pkg-config".
