arch-mips: Add MACHINEOVERRIDES variables to reduce duplication 

In some cases, each MIPS variant in a recipe requires a duplicate
line. Even if the passed flag is the same.

Add global MACHINEOVERRIDES variables for the following
 * mipsarch		: All MIPS
 * mipsarch{eb,el}	: All MIPS Big/Little Endian
 * mipsarchr6		: All MIPS R6
 * mipsarcho32		: All MIPS o32 Endian Independent
 * mipsarchn32		: All MIPS n32 Endian Independent
 * mipsarchn64		: All MIPS n64 Endian Independent
 * mipsarcho32{eb,el}	: All MIPS o32 Big/Little Endian
 * mipsarchn32{eb,el}	: All MIPS n32 Big/Little Endian
 * mipsarchn64{eb,el}	: All MIPS n64 Big/Little Endian

This is intended to reduce duplications in recipes

@ -32,6 +32,9 @@ MIPSPKGSFX_BYTE - This is defined as either blank and "64" for MIPS64 CPUs.
MIPSPKGSFX_ENDIAN - For bigendian hardware this is blank, otherwise it's
defined as "el".
MIPSPKGSFX_ENDIAN2 - For bigendian hardware this is "eb", otherwise it's
defined as "el".
MIPSPKGSFX_VARIANT_tune-<tune> - In the default tunings it is set to the
same value as TUNE_ARCH. In custom, optimized tunings, the value should
be modified to more precisely describe the tuning.
