Sorry for the going quiet, was out of town this week so didn't have a
lot of free time.

This definitely helps a lot for our case. Timings are not on the same
machine as my original email, but on one slower machine it takes the
worst case test case from 40 seconds back down to 11.5 seconds running
with the libtool wrapper; the unwrapped .libs/lt-* binary takes 11.2
seconds so the overhead is drastically reduced.

Thank you for looking into this!
