That's the standard behavior of flags.  You could
change the action to use $(CONFIG_COMMAND[1]), but
that's kind of hacky.

  Yes, you need to define a generator.  The
existing link action hard-codes the -Wl,
prefix, because it assumes that you are using
gcc to link.  There are already a couple
alternate linking generators for mingw and
cygwin.
