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.

Tokyo Cabinet is a library of routines for managing a database. The database is
a simple data file containing records, each is a pair of a key and a value.
Every key and value is serial bytes with variable length. Both binary data and
character string can be used as a key and a value. There is neither concept of
data tables nor data types. Records are organized in hash table, B+ tree, or
fixed-length array.
