Nick posted a patch to fix things.  are you guys fighting over who gets there 
first ? :)

the ppc/ subdir doesn't use common/, so there's no need to regen when it 
changes.  the changes you show here are just updated autotools, and ones i 
haven't bothered committing.  you may if you like, just providing info.

maybe it's me, but i also don't typically include the regenerated output in 
the diffs posted to the list since they're generally noise.  would rather focus 
on the things that the dev is changing.

i'd relocate this new code further down in the SIM_AC_COMMON definition.  maybe 
above the "# Dependency checking." line.
