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:
Import sigscheme version 0.8.0.

SigScheme is a R5RS Scheme interpreter for embedded use.

It features small footprint (64KB in library form on the 'small' configuration)
like SIOD and TinyScheme, low memory consumption (2-words per cons cell),
multibyte characters handling (UTF-8, EUCs and Shift_JIS) and more.

It is mainly developed to be the Scheme interpreter of uim.
