It is still the default Python on CentOS7 which is an even longer LTS
based on the recent CentOS changes. I would consider it a primary test tool
which should work on all hosts.
And we are already seeing the impact of the bsp-builder not supporting waf:
305 or ~1600 BSP builds failed because you can't build PowerPC BSPs

This brings up a discussion I have been having with Kinsey. He submitted BSP
variants for the aarch64 ilp32 and ip64 multilibs but is heading to making
BSP configure options. Not exposing them as variants makes them harder to
It is all the same code and same rtems-tester configuration information.
Would we rather have BSP variants for something like this or have to layer
more code to tweak BSP specific configure options when it really does
the code generated?
I am happy with clock speeds, memory address ranges, and RAM size being
configure options we don't push through automated testing. Hit the defaults
and move along. But configure options that substantially change builds like
switching the multilib variant feels different.
What do we want the rules to be?
