Hi,
I updated the webrev accordingly.
I'm checking for "ppc" and "64" now.
Best regards,
Goetz.

Hi, Goetz
I talked with David and we want you to add OS checks as generic_buildminimal1 does to avoid a confusion in future if
someone (as I did) try to build CORE on other platforms. CORE was one of our supported builds and someone can think that
this change will reenable it on all platforms which is not true.
Thanks,
Vladimir
