[PATCH, testsuite] Fix powerpc-specific portions of PR85326

[Bill Schmidt]

Hi,

This test fixes the part of PR85326 that involves powerpc test cases.
It removes support for .C tests in gcc.target/powerpc and moves the
one .C test from that directory to g++.dg with target constraints.
Tested on powerpc64le-linux-gnu.  Okay for trunk?

Thanks,
Bill
