Siddhesh Poyarekar 99f8dc9220 Fix -Wundef warning on PAGE_COPY_THRESHOLD ...

The PAGE_COPY_THRESHOLD macro is meant to be overridden by
architecture-specific pagecopy.h, but it is currently done only by
mach; all other architectures use the default.  Check to see if the
macro is defined in addition to whether it is set to a non-zero value.
