[FUZIX] make for z80pack fails with error ?ASlink-Warning-Undefined Global '_trap_reboot' referenced by module 'syscall_other' (#215)

I am trying to follow https://sinrega.org/?p=218 to build a Fuzix OS disk image and it fails with following  error:

prateem@prateem-VirtualBox:~$ tail -10 fuzix_build_failure.log

?ASlink-Warning-Undefined Global '_trap_reboot' referenced by module 'syscall_other'
make: *** [fuzix.ihx] Error 2

I was able to fix it by making the following changes (but I am not sure if this is the right fix):
