I left something implicit for the non-explicit testing
that may not be obvious: a full sequence for a test
seems to be something like:
A) from a pre-change context, build with the change
B) install the change and boot it
C) Try a native rebuild and install without any explicit
TARGET/TARGET_ARCH assignment.
Making it through (C) should test the non-explicit case
for the kind of environment involved.
Of course, if (B) fails or leads to failure in (C),
recovering via more from-source build activity in that
messed up environment could be difficult. Using explicit
TARGET and TARGET_ARCH assignments might help?
