Vicente Olivert Riera ad16eff64b mips: add support for R6 
Understanding the mips32r6 and mips64r6 ISAs in the configure script is
not enough. In order to have full support for MIPS R6 in FFmpeg we need
to be able to build it, and for that we need to make sure we don't use
incompatible assembler code which makes the build fail. Ifdefing the
offending code is sufficient to fix the problem.
