[PATCH] Enable EHABI by default on non-Darwin ARM targets

[Renato Golin]

  Hi Anton,

  I needed to get the test-suite bot running a few iterations before the end of the week, so I committed (r200388), we can make the new function more specific later, for now it's good enough. Thanks for the review!
