[patch] Fix builtin-explog-1.c. (take 2)

[Kazu Hirata]

Hi,

Attached is a revised patch to fix builtin-explog-1.c.

On H8, float is the only floating point math available, and types like
long double or double are the same as float.  Consequently, the
following test fails by the smallest margin.

 if (EXP(5.0) < (BASE)*(BASE)*(BASE)*(BASE)*(BASE) - PREC \
  || EXP(5.0) > (BASE)*(BASE)*(BASE)*(BASE)*(BASE) + PREC \

The patch relaxes PREC and PRECL if the target does not actually have
double or long double.

Tested on h8300-elf.  OK to apply?

	* gcc.dg/torture/builtin-explog-1.c (PREC): Make it the same
	as PRECF if sizeof (float) > sizeof (double).
	(PRECL): Make it the same as PRECF if
	sizeof (float) > sizeof (long double).
