It's not clear to me how this would fit into the build system. The
cross-compiled PostgreSQL build will be installed on the host system,
whereas <host-triplet>-pg_config will remain on the build system. But
we have no way of installing some bits here and some bits there. Then
again, installing a pg_config on the host system that contains
information for building on the original build system is wrong anyway.

One thing you could do is always install <host-triplet>-pg_config when
cross-compiling, and then have your surrounding package mechanism figure
out what to install where. Possibly make pg_config a symlink to the
above.
