Fedora doesn't properly define MACHTYPE=x86_64, so the Makefile fails to 
define __x86_64__ and tries to compile PTLsim for a regular Pentium 4 instead 
of the Core 2 based Xeon chip you have (which obviously does support 64-bit).

The easy workaround is to change the first part of the Makefile to comment 
this test out:

# ifeq ($(findstring x86_64,$(MACHTYPE)),x86_64)
__x86_64__=1
# endif

This should force it to compile for 64-bit.
