This PR adds support for GPU offloading when building with gcc, in addition to the previous clang support. Tested on the Cirrus cluster in Edinburgh with both a version of gcc that supports offloading and one that doesn't.
I also removed the -stdlib=libc++ stuff from the GPU detection function. I realised that was pointless because neither of the GPU compilers have that flag in the first place.
