soft-fp: Properly check _FP_W_TYPE_SIZE [BZ #24066]
quad.h have

 #if _FP_W_TYPE_SIZE < 64

union _FP_UNION_Q
{
  Use 4 _FP_W_TYPEs
}

 #else

union _FP_UNION_Q
{
  Use 2 _FP_W_TYPEs
}

 #endif

Replace

 #if (2 * _FP_W_TYPE_SIZE) < _FP_FRACBITS_Q

with

 #if _FP_W_TYPE_SIZE < 64

to check whether 4 or 2 _FP_W_TYPEs are used for IEEE quad precision.
Tested with build-many-glibcs.py.

	[BZ #24066]
	* soft-fp/extenddftf2.c: Use "_FP_W_TYPE_SIZE < 64" to check if
	4_FP_W_TYPEs are used for IEEE quad precision.
