Probably the easiest if you write a shell script for the compiler that
invokes the compiler for compiling, and the two other programs for
linking.

The script named "compile" that comes with Automake has logic how to
easily distinguish between compile and link stage, you can probably use
that as a starting point (even if it serves a completely different
purpose.)

Then, just
  ./configure CC=your-script

If you are using libtool and shared libraries, you could probably get
away with overriding some of its variables; look at $archive_cmds,
$archive_expsyms_cmds and maybe $old_archive_cmds.  (You may still need
to override the linker for creating programs then, but that isn't hard
to do.)

That sounds like more work; but you haven't stated which compiler you
use, so I don't know.  It may be a better long-term solution though.

Cheers,
