pkgconfig and its imitations (such as our config scripts) share this
problem with libtool.

Don't forget the .la files :)  That's actually the canonical way to do
it, I think (and yes, it's a PITA).  For GPGME and friends, you can also
just build and install for the cross-compilation build paths, and
use the --with-gpg and --with-gpgsm etc. options to specify the
hard-coded target file names of the crypto engines.  The result is
relocatable except for the .la and -config files, which need to be fixed
up anyway.  (So, if you want to develop on build and target, you
absolutely need two copies of those files, no matter what you do).

Thanks,
