Disable double strtod in ARM-simulator.

The ARM simulator is compiled for 32bits. On Linux the floating-point
operations are hence invalid for the simulator too.

Fix double-rounding in strtod.
...
Don't use floating-point operations on Linux,x86 to compute strtod. Since the
floating-point stack on Linux is set to 80bit double rounding may occure.
When falling back to gay_strtod append several '0's so that Gay doesn't take
the same shortcut either.

If there are few non-zero digits and the 10^exponent fits into a double then
we can compute the result using 1 (or 2) double operations.
