.pc file installation location

[Jeff Squyres]

Greetings.  I'm creating .pc files for our project (www.open-mpi.org).

Where does one typically install these files?  I see that pkg-config(1) v0.23 says:

    ...By default, pkg-config looks in the directory prefix/lib/pkgconfig for these files;...

Does that really mean $prefix/lib/pkgconfig?  Or does it actually mean $libdir/pkgconfig?

It doesn't matter to me either way; I just wanted to set our Makefile.am's to install our .pc files in the "usual" location.

Thanks!
