uclibc: enable mips{32,64}r6 support

The config for ISA choice is removed for a long time as
the buildsystem does not pass -march=mips* to the compiler anymore.
For mips{32,64}r6 support NAN selection is required.

Tested with qemu mips32/mips64 defconfigs.

A small patch is required. Bug found while testing qemu defconfigs.
