[Buildroot] [PATCH v2 00/12] RFC: ARC port

[Mischa Jonker <Mischa.Jonker@synopsys.com>]

Hi all,

Thanks for the prompt feedback that I have received on the patches. Here's
a new revision of the patchset to introduce ARC support in BuildRoot; I
think I have addressed all the comments received from Thomas and Arnout.

Thanks,

Mischa

Changes in v2:
 * BR2_ARC_SITE hardcoded now, and moved to Config.in.arc
 * makeinfo dependency removed from binutils
 * Added 3.9-rc8 kernel headers
 * Patches split where suggested
 * Removed ARC-specific uClibc config
 * Moved ARC-specific binutils out of the choice menu
 * Introduced explicit BR2_arcel, BR2_arceb symbols a la microblaze
 * Added a patch that cleans up GCC architecture dependencies
 * Fixed patches for binutils, gcc
