48060bc2d7 Fix bug which has kept ld.so from being built for some time: 
<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.

7d468e4a0c Iff __m68k__, use a `slight hack' to determine the magic of the executable 
we're doing a dynamic link for, and change the page size used for offset
and size calculations if necessary.  Allows the same ld.so to be used with
mixed m68k4k and m68k8k executables and libraries.

Thanks a million to Gordon Ross for the help in making this work!
