I think it is expected since I had to change the objdirs for build/cross
tools again to fix your report.

I am very confused how I never hit the issue you and Matt ran into. I
had this commit sitting in my test branch for days.  It may just be due
to SYSTEM_COMPILER getting triggered.  There's so many combinations of
options in the early build that it's impossible to test all of them.

Anyway if it continues to happen please also pass -dM to your make as it
will tell us why it is rebuilding.
