The other way around (ppc building for intel) does not seem to work:
to make configure finish you have to force the compiler to use the  
universal sdk adding to the CFLAGS -isystem... and -Wl,-isyslibroot - 
Wl,...

--target=i686-darwin does not really work, as the configure does not  
detect darwin, $_darwin does not get set and no macos libraries  
detection happens; after adding the darwin architecture to the  
configure script, you need to force the compiler to use sse3 with - 
msse3 or the macos api detection will still fail. after that  
configure will run (trying and failing to execute some cross compiled  
binaries), but make will fail complaing that about something not  
being a valid 386 opcode.
