The crosstool package from Dan Kegel did a good job for this. Not sure
it's currently maintained though. It was a very useful project, it's a
shame if it does not live on. It would be good to have up-to-date and
tested compilers for various architectures available on kernel.org,
ideally with access to a package that helps building compilers for
various architectures.

Thanks,

Mathieu
