toolchain: add support of ARC architecture This includes binutils, gcc, gdb and uClibc-ng. Latest release of ARC gcc (as of today it is "arc-2015.06") is based on upstream gcc 4.8.4. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/gcc Latest release of ARC binutils (as of today it is "arc-2015.06") is based on upstream binutils 2.23. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06 Latest release of ARC GDB (as of today this is "arc-2015.06-gdb") is based on upstream gdb 7.9.1. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb Note that for binutils and gdb that come from unified git repository (which is the case for upstream binutils/gdb today) we need to disable building of gdb in binutils and binutils in gdb hence in binutils: ------>8------ --disable-sim --disable-gdb ------>8------ and in gdb: ------>8------ --disable-binutils --disable-ld --disable-gas ------>8------ Also in gdb we disable sim because if the following breakage while building with it: ------------>8------------ /usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \ -mono -fast -pbb -switch sem5-switch.c \ -cpu a5f -infile ./mloop5.in \ -outfile-suffix 5 unknown option: bash Makefile:699: recipe for target 'stamp-5mloop' failed make[7]: *** [stamp-5mloop] Error 1 ------------>8------------ Cc: Felix Fietkau <nbd@openwrt.org> Cc: John Crispin <blogic@openwrt.org> Cc: Jonas Gorski <jogo@openwrt.org> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@47438 3c298f89-4303-0410-b956-a3cf2f4a3e73

target: split jffs2 NAND out of jffs2 Make jffs2_nand a separate option so this can be triggered without forcing jffs2 images for nor targets.

buildroot: allow enabling MIPS16 user-space build Enabling MIPS16 is made conditional on advertising the "mips16" feature for a specific target since it requires support from the CPU (HAS_MIPS16) and the actual use of MIPS16 for building packages (USE_MIPS16).
