MIPS MACHINE_OVERRIDES can be used to provide the same objarch.h files for MIPS pre-R2 and R6 ISA versions. Use them to reduce duplication in supporting MIPS R6 ISA (From OE-Core rev: a169f11cee3f4288467120cbc363f5e664b86f0c) Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
