testsuite: Adjust rs6000-ldouble-2.c for switch to -std=gnu23 by default
[PR117663]
-std=gnu23/-std=c23 changes LDBL_EPSILON for IBM long double, see r13-3029
and
https://gcc.gnu.org/pipermail/gcc-patches/2022-October/602738.html
for details.
That change even had a note:
"and when we move to a C2x
default, gcc.target/powerpc/rs6000-ldouble-2.c will need an
appropriate option added to keep using an older language version"
The following patch just implements it to fix rs6000-ldouble-2.c regression.
