Out of curiosity  - A number of tests are gated off by the target
triplet arm*-*-*eabi* , I wonder how many of them actually run if you
test with arm-none-linux-gnu . Also given this is the pre-EABI linux
triplet, so I'd prefer not to conflate this with the use of the
triplet arm-none-linux-gnueabi(hf).
