<bsd.prog.mk> was being included before an .if !defined(NOPIC)
which added rtld to the SUBDIRs. This was so that the definition
of NOPIC would get picked up. Unfortunately, this is WRONG, because
after <bsd.prog.mk> is included you shouldn't be able to touch SUBDIR
as the magic has already happened.
However, a complementary bug in the .mk files kept anyone from
noticing until now.
Fixed by moving the include of <bsd.prog.mk> to the bottom and
including <bsd.own.mk> above the .if !defined, which is the correct
way to do this sort of thing.
