You might be interested in my patch to reduce the space complexity for
piecewise linking. See https://savannah.gnu.org/patch/index.php?6104

Thanks for the report and patch.  I agree that quadratic space
complexity is undesirable, and outweighs spawning more rm processes
(the linking itself is typically much more costly here).  We should
however strive to remove each file exactly once (to facilitate RM=rm
rather than RM='rm -f').

I'm currently testing the patch below.  OK to apply (if it shows
no problems)?

Since it is fixing a bug, then yes, as long as testing doesn't reveal
any regressions, please apply.

Cheers,
        Gary
