FWIW, I just learned it's possible to pass a list of target boards to --target_board:

  --target_board='unix native-gdbserver native-extended-gdbserver'

And it gives a combined result at the end.  So I'll make myself an alias to test on all
the commonly used boards, probably:

- cc-with-debug-names.exp
- cc-with-dwz.exp
- cc-with-dwz-m.exp
- cc-with-gdb-index.exp
- debug-types.exp
- dwarf4-gdb-index.exp
- fission-dwp.exp
- fission.exp
- native-extended-gdbserver.exp
- native-gdbserver.exp
- native-stdio-gdbserver.exp
- readnow.exp

When working on a single test, it's usually not to long to run them all.  Of course, it's
not really practical to run the complete testsuite twice (before and after) for each board
for every change we do...
