Using a compiler with a different host triplet is considered
cross-compiling, even when it is for the same architecture as the
build system. With such a cross-compiler, it is still valid to
optimize builds with --cpu=host. Make the condition that aborts in
this case into a warning instead, since a cross-compiler for an
incompatible architecture will fail with -mtune=native anyway.
