elf: Don't check FCR31_NAN2008 bit for nanoMIPS
nanoMIPS is always NaN2008 compliant, and rules for checking FCR31's NAN2008 bit are obsoleted. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Aleksandar Markovic <amarkovic@wavecomp.com> Signed-off-by: Stefan Markovic <smarkovic@wavecomp.com>
