make tinderbox effectively does that, but at a bit more expense.  amd64
doesn't build GCC 4.2 by default, so the simplest way is to build a kernel
for a non-clang platform, e.g.:

make TARGET=sparc64 kernel-toolchain
make TARGET=sparc64 buildkernel

(Note you only need to do the kernel-toolchain step once or after toolchain
changes like compiler upgrades.)
