[Buildroot] [PATCH 0/7] RFC: ARC port

[Mischa Jonker]

Hi BuildRoot developers,

In the following patch series I've added ARC support to the "master" tree
of BuildRoot. As ARC support is not yet in all upstream open source packages,
I've taken the freedom to add an option for an additional download site, from
which ARC-specific versions of gcc, binutils, etc. can be downloaded.

ARC will be in Linux 3.9, so that would be the first package that can be
removed from this ARC-specific download site.

The below patchset builds the toolchain, and a working root file system. Most
simple packages build OK, but mplayer for instance does not have ARC support,
and there are probably others as well.

Could you please have a look at the patches and let me know what to do to
make them BuildRoot-worthy?

Thanks,

Mischa
