Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Do require C as const gets defined away otherwise with rather strange
results. Also use ELF for the YASM output on DragonFly and put an
assertive case therein in the hope to detect other systems with a less
mysterious error.

Initial import of MAC: short for Monkey's Audio Codec, a lossless
audio codec (files with the .ape extension).

This is the MAC Linux port. It has autoconf and automake stuff and
some slight changes to the code.
