Cross compiling with pkg.m4

pkg.m4 doesn't behave in a very rational way, when configured with
--host=xyzzy


All the PKG_CHECK_MODULES macros continue to find the local modules,
not the ones for target xyzzy.    Consequently, the build fails when
the compiler/linker can't find the header/library for the necessary
packages.

Of course, one can get around this by setting the PKG_CONFIG_LIBDIR
environment variable prior to running ./configure but I think that
most people won't know that it's necessary, and it seems redundant to
me, because of the --host flag.  

Shouldn't PKG_CONFIG_* find only packages pertaining to
the target architecture?

J'
