I built a full pkg set on an Ampere eMAG on 2019-09-11, and again on
2019-11-04 after this change went in. The second build included
TRYBROKEN so tried to build more ports and took slightly more time
overall, but comparing the overall build duration (wall clock) of
various ports is illustrative.

llvm90 took the longest to build; it was 21:15:58 in the first run and
19:54:32 in the second. qt5-webkit went from 12:13:21 to 11:39:21.
rust went from 15:14:46 to 13:49:50. firefox from 7:24:21 to 7:08:35.
