rs6000: don't expect __ibm128 with 64-bit long double [PR99708]

Browse Source 
When long double is 64-bit wide, as on vxworks, the rs6000 backend
defines neither the __ibm128 type nor the __SIZEOF_IBM128__ macro, but
pr99708.c expected both to be always defined.  Adjust the test to
match the implementation.
