Of those, I prefer pkgconfig-32bit(pango) as the file pkgconfig name remains
pango.pc

I think for the provides this is rather ok, but I see a prolem with the
requires (which is possibly what you meant as well with noarch?!)

a .pc file installed in /usr/share could potentially end up in a noarch
package, so there won't be a -32bit and no pkgconfig-32bit(foo) provider
available

There is for example /usr/lib64.pkgconfig/xfixes.pc that Requires: xfixesproto
(noarch, un /usr/share)

Even worse: /usr/share/fixesproto has Requires: xextproto - which in turn is
arch-dependent again. Expressing this as dependency sounds close impossible
