[Buildroot] [PATCH v3 00/11] ARC port

Hi all,

Now that 3.9 has been released, ARC doesn't depend on its own kernel anymore.
This is reflected in the patch set, furthermore, bison/flex host dependencies
have been removed (thanks to Thomas for his input).

The GCC version architecture dependency cleanup patch is not really related to
ARC, and I will come with a proposal as a separate patch.

The patch set is also published on our github site: 
https://github.com/foss-for-synopsys-dwc-arc-processors/buildroot

Changes in v3:
 * removed GCC arch-dependency cleanup patch (should be discussed separately)
 * 3.9-rc8-->3.9 kernel headers
 * Added bison/flex host dependencies

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
