[Buildroot] [PATCH v4 00/12] ARC port

[Mischa Jonker]

Hi all,

Accidentally the first patch of the series was missing in v3 (wrong usage
of git format-patch command on my side...). So this is a resend of v3, but
now with an extra patch!

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

Thanks, Mischa

Changes in v4:
 * re-added missing bison/flex host dependencies patch for gcc

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
