Yes, but it moves the calculation from generic to x86-specific code,
which makes it problematic.

I never figured out how to make a generic rule in Kbuild (unlike in
standard GNU make) depend on a helper application, but doing a helper
application for this is probably the sane thing.

Either this, or use Perl, which handles this kind of crap sanely.  I'm
really less than half joking.
