The rebuild of the ports rebuilt x11/pixman earlier in the sequence
than I had guessed so it took less time to get to that point:

[00:51:26] [03] [00:00:00] Building x11/pixman | pixman-0.34.0
. . .
[00:54:15] [03] [00:02:49] Finished x11/pixman | pixman-0.34.0: Success

So -r449285 has avoided using clang's internal assembler.
