-# output file into the current directory, instead of the 
-# target directory. E.g. "make /tmp/foo.o" causes "./foo.o" to be
-# created (!). Since OpenBSD doesn't support LOAD-FOREIGN, this
-# doesn't matter much, since it punts with UNSUPPORTED-OPERATOR
-# instead of not finding the file. But it'd be nice to straighten
-# this out, if only so that sbcl-foreign-test-*.o clutter
-# doesn't pile up in this directory. Maybe some time when I have
