If the goal is to generate a 64bit binary so users can easily run it 
without variants, you don't need a new file but to edit the Makefile adding:

     include $(abs_srcdir)/../utils/newer_64.mk

     %_64: CPPFLAGS += -D_FILE_OFFSET_BITS=64

In this way you will have a 64bit binary for each test in the folder. At 
that point, to switch between syscalls according to the 64bit 
architecture definition is easy and runtest file will need to be updated 
accordingly. If you take a look at the other test cases you will find 
many examples on this method.
