Aiui arm-eabi and e.g. arm-linux-gnueabi (the latter is what I
use) use different emulations, yet the test cases get enabled
for all of arm-*-*. armelf_linux.sh hasn't got the additions,
which I understand is the reason for the .noinit and .persistent
test failures on 2.36.

If that's correct, the question is whether the script needs
adding the settings, or the tests need excluding.
