No, he's suggesting (I'm pretty sure), that the Sun compiler would only
be used to build gcc, so gcc might compile the kernel faster, but since
it's gcc generating the kernel, it should output the same code as a gcc
that was compiled by some other compiler (including gcc itself).

You'd have to rewrite all the makefiles and build scripts if you wanted
to get NetBSD itself (kernel and userland) compiled by the Sun compiler,
and it's likely to not work as-is (inline-assembly and other compiler
dependencies).
