Well, the LDFLAGS, CPPFLAGS, CFLAGS approach is intrinsic to 
autoconf/automake.

It's just a standard use-case of autoconf/automake, which doesn't need 
special casing. It also is the standard use-case, how distribution 
packagers apply autoconf/automake.

Exactly. There is a lot of confusion about this topic around, and a lot 
of uncooked recipes around, seemingly stemming from people who never 
used multilibs and multiarched systems.

These kind of config scripts are problem-zone of their own, because many 
of them are not multilib-ready.

E.g. many projects *-config scripts which stem off from early 
gtk-config/glib-config ... unfortunately, these were not multilib ready.

The feature pkg-config adds, is it providing a systematic (though 
arguable) approach - But this is yet another topic.
