greatly simplify and speed the build process by doing the steps
manually instead of building the lang/gauche wrkdir before starting
the module compile.
pkg-plist is no longer necessary, using PLIST_FILES in the makefile
instead of having two PLIST_SUB lines in the makefile to handle the
two files in pkg-plist.
forces a link against libgdbm, which SHOULD fix the problem noted in
ports/86293 if the issue I was able to replicate was indeed the same
tested on i386 5.4 and 7, using athlons.... assuming the link flags
aren't different for other arch's... additional testing/reports
I'll take it.
