Ok, so I tried adding HAVE_LLVM=yes but then I see:

/usr/src/external/gpl3/gcc/dist/libgomp/oacc-init.c:632:21: error: unknown attribute '__optimize__' ignored [-Werror,-Wunknown-attributes]
int __attribute__ ((__optimize__ ("O2")))
                    ^
/usr/src/external/gpl3/gcc/dist/libgomp/oacc-init.c:635:10: error: use of unknown builtin '__builtin_acc_on_device' [-Wimplicit-function-declaration]
  return __builtin_acc_on_device (dev);
         ^
/usr/src/external/gpl3/gcc/dist/libgomp/oacc-init.c:635:10: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes]
3 errors generated.

I guess I have to turn off the gcc build as well, but for now I'd like
to have both compilers...
