crossroads: fix pgm build errors

crossroads builds an internal libpgm from source, but that causes
build errors because of a conflicting struct definition with OSX
`netinet.h`.  So instead of dealing with that, link crossroads
against our libpgm-5.2 which builds without error.  Add a couple
of ENV vars to override `pkg-config` and help crossroads find
the libpgm we now depend on, which it can't find otherwise because
it's looking for `openpgm-5.1.pc` and we offer `openpgm-5.2.pc`.
Crossroads passes `make check` on 10.8.2 with XCode-4.5.

Fixes #15217

Closes #15255.
