Enabled building of x86_64 code on Mac OS X (Alexander Graf)

Mac OS X 10.5 supports 64-bit userspace on an x86_64 kernel and
by default uses 32-bit userspace applications, so the detection for
the host architecture fails.

This patch enabled building of x86_64 code on x86_64 capable CPUS
with Mac OS X.

+# on Leopard most of the system is 32-bit, so we have to ask the kernel it if we can run 64-bit userspace code
+is_x86_64=`sysctl -n hw.optional.x86_64`

This results in an error message on OSX/ppc:

second level name optional in hw.optional.x86_64 is invalid

The attached patch silences this error output.
