Given a string like this:
  "123.456 E+12"
strtof and strtod return 0.0 and point to the first character of the string,
meanwhile strtold returns the value 123.456 and points to the space character
between mantissa and "E+12".  I assume that all functions should behave
identically in this case.

	* src/libc/ansi/stdlib/strtold.c: Do not return the mantissa of a
	floating point number if the exponent conversion failed.
