arch/mips: add option for toolchains supporting -mnan
-mnan option was added in gcc-4.9.0 so make sure that users cannot select the NaN mode when using toolchains that have a gcc older than 4.9.0, and also make sure that the -mnan option is not passed at all to the toolchain-wrapper and target cflags.
