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.
Regstrapped on ppc64-linux-gnu. Also tested with ppc64-vxworks7r2
(gcc-12). Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/powerpc/pr99708.c: Accept lack of
__SIZEOF_IBM128__ when long double is 64-bit wide.
