Sounds like a reasonable compromise to me.  Only snag is that if you
build a 32 bit kernel, make clean, change config for a 64 bit kernel,
then make again, you will build a 64 bit kernel with the wrong offset.h.

Would be nice if 'make' could verify that the offset.h ifile was correct,
without changing it (and so triggering dependencies).  If it could do
that, it could regenerate it only if it was wrong.
