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:
Avoid embedding $NetBSD\$ and similiar constructs in-tree files.
The strings would be picked up for +BUILD_VERSION and create mismatches
when using ident on the same files.

3.13: add BUILDLINK_ORDER lines.

Log message:
Changed two lines in the generated buildlink3.mk files. For quite a long
time, the !empty(BUILDLINK_DEPTH:M+) lines confused me, so I changed
them to be ${BUILDLINK_DEPTH} == "+", which has the same effect. Changed
the version number to 3.12.
