LOG: [libcxx] Move Linaro 32 bit armv bots to buildkite

Instead of setting mcpu like the previous bots,
set the target triple.

Each config builds either Arm only or Thumb only
code. This gives us some coverage of thumb specific
issues.

The new agents on Linaro's side are running on v8 hardware
so will report arch "armv8l" just like the v8 bots.
(and buildkite can choose any of them for v7/v8 jobs)
