Fix strtof ("-nan") returns positive NaN

strtof ("-nan") returned positive NaN instead of negative NaN.
strtod ("-nan") and strtold ("-nan") return negative NaN.

Linux glibc has been fixed
that strto{f|d|ld} ("-nan") returns negative NaN.

This commit makes strtof preserves the negative sign bit
when parsing "-nan" like glibc.
