Just a note to let you know that even though I didn't had the time the
past weeks to work on this, supporting Codesourcery toolchains in
Buildroot is definitely on my TODO-list. So, sorry if it wasn't ready
for your project, but it's for sure something I'd like to see supported
in Buildroot.

Thanks for all your investigations. When I'll have a little more time,
they will be very precious to give an idea where to start.
