[FFmpeg-devel] [PATCH v3 04/14] mips: remove --mips64r6 configure option

[Vicente Olivert Riera]

Having a configure option with the same name as a MIPS ISA is confusing,
so better to remove it. This option was being used to add some
optimizations to a specific core (i6400). We will add the optimizations
just when the i6400 core has been detected, in a later patch.
