[PATCH] powerpc: Automatic CPU detection in preconfigure

[Joseph Myers]

All preconfigure fragments are always sourced by configure; code in a 
preconfigure fragment needs to be inside a case statement or other check 
that $machine is a system for which that fragment is applicable 
(preconfigure fragments are part of the mechanism that maps from 
configured machine names to the list of sysdeps directories relevant to 
that configuration).

Thus, the 'if test -z "$submachine"; then' code added by this patch all 
needs to be conditioned so it only runs for powerpc.
