fix printf precision specifier for hex floats on non-ld80 archs

the code to perform rounding to the desired precision wrongly assumed the long double mantissa was an integral number of nibbles (hex digits) in length. this is true for 80-bit extended precision (64-bit mantissa) but not for double (53) or quad (113). scale the rounding value by 1<<(LDBL_MANT_DIG%4) to compensate.
