I'm not sure what you mean by 'cross-ng'. Do you mean 'crostool-NG' ?

If so, support for toolchain using the Linaro gcc (and gdb?) is planned.

Attached is a test-patch that is absolutely untested (at least it downloads
and extracts the tarballs).

It adds support only for the lattest Linaro gcc version. Please apply and
report whether it works for you. If so, I'll rework it to be a bit more
generic.

(CC: Thomas, as we already discussed the subject live at FOSDEM).

Regards,
Yann E. MORIN.
