sometimes the build would fail because of "missing" packages that
weren't actually missing (this only happened in ports that aren't
committed yet).
Rewrite the FASL placement code using the asdf-binary-locations
extension, which is already included in the cl-asdf port but needs
to be installed from ports when building for SBCL (which has its
own ASDF code). The binary-locations code generates paths unsuitable
for PLISTs, therefore it has been overridden with
lisp-specific-fasl-subdir.
Because of the new code, PLIST generation for cl-*-sbcl and cl-*-clisp
ports is now entirely automated.
All dependent cl-* ports are upgraded (obsolete code removed,
PORTREVISION bumped).
Introduce bsd.cl-asdf.mk to automate the compilation and installation
of Common Lisp libraries using the ASDF framework.
Currently it supports building FASL files on SBCL and CLISP, to
support the ports that already exist in the ports tree.
This should help bringing in more cl-* ports from the ASDF repository
without excessive code duplication.
