This is starting to turn into a bikeshed, but anyway...

The canonical way to compile a kernel is to use buildkernel and compile modules
along with the kernel.  Other configurations are supported too, of course.

The key word in your note about clang is 'soon' as in 'not yet'.

Besides, when I see a bug report with a dmesg *I* want to immediately know what
compiler was used there.
