Begun to add support for non i386 architectures, with the help of Chris

Browse source 
Original commit message from CVS:
Begun to add support for non i386 architectures, with the help of Chris
Emerson.  Added bits to configure to figure out architecture, and added
some alternatives for PPC.  Should cause no problems on i386, but I'll
check after this commit, but doesn't yet work on PPC by a fair way...
