From e680b230a7235016fc8c322137f9d4dd4331065f Mon Sep 17 00:00:00 2001
From: tv <tv>

Subject: Merge down deferred EVAL_PREFIX handling from tv-derecurse branch.

Also move its definition later in bsd.pkg.mk, so that it actually works
for compiler/*.mk (which is why those files originally had to provide
"defaults" for their variables -- they never did get evaluated).
