description:
Reduce length of command lines executed by not appending some options that
we've already seen:

-[DILR]*|-Wl,-R*|-Wl,-*,/*
        These are all only useful the first time we see them.  All other
        instances are redundant.

-l*
        Extra libraries are suppressed if they're repeated, e.g.,
        "-lm -lm -lm -lX11 -lX11 -lm -lm" -> "-lm -lX11 -lm".

The screen output is still likely to be very verbose, but you can check
in work/.work.log to see the actual commands executed.
