You give the arch

  ./config/gmakegentest.py --petsc-arch=arch-master-debug

I have encountered a strange behavior, perhaps only on my machine, where if
I do not run

  PETSC_ARCH=arch-master-debug
./config/gmakegentest.py --petsc-arch=arch-master-debug

then it does not update correctly.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
