I don't follow. If I do not specify abi when cross-compiling to ARM, then:

- Compiler does not care much, it just uses the default one
- Boost.Build does not care either, since all ARM alternatives in boost.context
   have the same ABI

What am I missing? Maybe I should submit a pull request, and you'll point out
in which cases it will result in compilation failure or wrong compilation options?

Thanks,
