It doesn't happen every time. Its some kind of race condition I guess.
For example it worked so that I could time how long it takes (below).

It happens with FreeBSD /usr/bin/make.

I installed GNU make, and GNU make always compiles correctly. But I think GNU
make isn't parallelizing the compile for some reason:

time gmake -j 2:
    35.946u 9.269s 0:47.93 94.3% 1428+1791k 0+1726io 0pf+0w
 
time make -j 2:
    38.183u 9.476s 0:30.25 157.5% 1478+1863k 0+2450io 0pf+0w
