christof added a comment.
Added a test for arm-none-eabi selection
Note that the selection mechanism in the Baremetal driver is rather weak. It does not seem to respond on `-mthumb`, `-march` and `-mcpu` options. The cc1 options show a normalized triple, but the sub-architecture suffix of compiler_rt is the argument exactly as typed on the command line. I'm not going to fix that in this patch, but maybe we want to record this problem somewhere, so we dont forget?
