Cross-compiling is difficult and requires considerable knowledge when the given configuration isn't well tested.

I would suggest using crosstool-ng and seeing if they have such a cross configuration already setup.

I know it's possible because there are people that cross compile Sourcery CodeBench sources so they can target ARM GNU/Linux from OS X which is basically the same thing.

I don't know what could be going wrong here and it's a deep and dark rabbit hole that could take days of intense work to figure out.

Sorry to be so dour about it :-(

Cross-compiling from Mac OS X is not something I see anyone testing frequently.

Cheers,
Carlos.
