Well, pkg-config already places .pc files under /usr/lib instead of
/usr/share, so the intention is clearly that .pc files _are_
arch-dependent. The nice thing is that users won't even notice if we
change the default search path from /usr/lib/pkgconfig to
/usr/lib/<arch>/pkgconfig (the existing .pc files of course have to be
relocated, but that will be part of the multiarch transition).

pkg-config is usually run by configure, way before gcc is invoked. So
we need a way to tell pkg-config the desired architecture. The simplest
thing is to install a wrapper that sets PKG_CONFIG_LIBDIR before calling
the real pkg-config.
