The native part builds nicely. Only cross build fails:

gcc: error: unrecognized argument in option ‘-mcmodel=tiny’
gcc: note: valid arguments to ‘-mcmodel=’ are: 32 kernel large medium small
gcc: error: unrecognized command line option ‘-mlittle-endian’; did you mean ‘-fconvert=little-endian’?
gcc: error: unrecognized command line option ‘-mstrict-align’; did you mean ‘-Wstrict-aliasing’?

Which is because for some reason the build system defaults to the host
toolchain. Where should I look in the code to trace the toolchain
selection?

By the way, I'm using the ARM (Ltd) released toolchain (version 8.2.1),
not the Linaro one that the wiki mentions. But I don't think that should
matter for the toolchain selection.

I'll try that next week if image build doesn't work for me. But I really
prefer to be able to build this image.

Thanks,
