[testsuite] [ppc] add -mfloat128 to pr67808.c
gcc.target/powerpc/pr67808.c in some cases expects both 128-bit long
double types to be defined, but -mlong-double-128 doesn't guarantee
that without -mfloat128 on targets that would get the IEEE128 type as
long double. Add -mfloat128 to ensure the desired IBM 128-bit
floating-point type is available as expected.
for gcc/testsuite/ChangeLog
* gcc.target/powerpc/pr67808.c: Add -mfloat128, and tolerate
its warning.
