Upgrade to ASDF 2.017.
From now on, asdf-binary-translations is no longer supported upstream.
Therefore, we use the new asdf:initialize-output-translations
function with the same logic as before.
SBCL 1.0.49 already has a bundled ASDF 2, which caused all cl-*-sbcl
ports to fail. The upcoming Clozure CL 1.7 will also need ASDF 2
support.
Upgrade to version 1.374 and cleanup.
The asdf-init.lisp script was changed to support the bundled ASDF
libraries in lang/ccl and lang/sbcl. Therefore, it can be safely
loaded by both (also by lang/clisp) to enable the ASDF framework.
