That's a lot of source bloat for what it's worth.  Wouldn't it be easier to
set the busses to have `needs-flag' in files.sparc, and #if-conditionalize
the appropriate code?  With needs-flag and use of the proper
config-generated .h file, as long as you do the proper "make depend", it
will rebuild those files that change with these flags when appropriate.
