Responsibility was formerly split between Makefile.global and pgxs.mk. As a result of commit b58233c71b93a32fcab7219585cafc25a27eb769, in the PGXS case, these variables were unset while parsing Makefile.global and callees. Inclusion of Makefile.custom did not work from PGXS, and the subtle difference seemed like a recipe for future bugs. Back-patch to 9.4, where that commit first appeared.
