[testsuite] [ppc] compile [PR112822] with -mvsx
g++.dg/pr112822.C uses altivec vectors explicitly, but it expects this
feature to be enabled by default on targets that recognize the
attribute, which is not a given on older ppc cpus, where the compiler
recommends recompiling with -mvsx.
Since it's just a compilation test, we don't seem to need to test for
e.g. assembler support.
