Actually, we should already be able to do that if --track-flags is
enabled. (Assuming that, --install-prefix is one of the flags tracked
by that option -- it it isn't, it should be.)
Another approach would be to get --make to look up the install name of
any already generated .dylibs, and force them to be relinked if they
don't much the compiler's current setting of --install-prefix.
I can take a look at the latter.
