Thanks for everyone's help.  It wasn't a kernel problem but a kernel
*build* problem!  The culprit was Makefile.i386.  Kudos to

for putting me on the right track.  The i386 makefile didn't clean up
everything it builds.  As a result the *assym* files are never
rebuilt and the .s files are always compiled with the configuration
of the first make of the first config in the directory.

The -current Makefile.i386 fixes this particular problem.
