FWIW there's a free-as-in-beer edition of xlc for Linux (various distros, POWER only) so you could use qemu, though of course there will be differences WRT AIX especially around linking, and I suppose a big part of that work would be precisely understanding stuff like linker details. It looks like we have two xlc 12.1 compilers in the farm, but those compilers are EOL'd[1]. The current release is 16.1, and we have one of those. The interesting thing about 16.1 is that you can invoke it as xlclang to get the new clang frontend and, I think, possibly use more clang/gcc-ish compiler switches[2].
