The new version is wrong, but it is difficult to come up with a right
version. I have done my best with the following logic

0) If you are using the dynamic FFI (i.e. LOAD-FOREIGN-LIBRARY is
evaluated at the toplevel on an Intel machine), then let the shared
library loader guess what to do.

1) Otherwise, if the argument is a pathname, or the namestring of an
existing file, add the namestring to the list of libraries the code is
linked with.

2) Finally, if it is a string or a symbol, try guessing the name of a
shared (unix) or static (*.lib, windows) library to link the code
against.

Please complain if it does not work as expected :-)
