Comment (by ryandesign):

 The libtermkey port is one that runs into this problem:

 If this is the correct syntax for telling libtool what compiler you want
 it to use, then indeed it seems to be honoring it when compiling but
 ignoring it when linking. I would want to fix that in libtool, not in each
 individual port that uses libtool.

 Christopher, you mentioned this is a long-known issue... do you know the
 upstream bug report URL?
