(1) How many upstream projects will take back changes to make their
foo-config scripts depend on pkgconfig?  I'm afraid this proposed
solution will mean we end up maintaining many local forks of foo-config.

(2) pkg-config isn't psychic either.  As near as I can tell from a quick
read of its man page, the only way it can solve the problem is if
rpmbuild sets PKG_CONFIG_PATH to select either 32- or 64-bit libraries.
While that's adequate for solving our own build problems, it doesn't
help for people doing ordinary source builds of library-using software;
from their point of view foo-config is still broken.  And this makes it
even less likely that any upstreams will take back the foo-config
changes, because the "solution" depends not only on pkgconfig but on a
worldview that says RPM is the only build environment that matters.
