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.

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