This builds fine for me on Wily's kernel;

root@p8tul13-lp1:~/HID_module# ./compile.sh
Please make sure you have installed kernel-devel package.

Please close this defect; this was opened against an internal build
which Canonical can't / shouldn't support, and should not be in bugzilla
or launchpad.

  == Comment: #3 - ==
  To me it  looks like packaging issue with linux-image/linux-header package.

  Out of all the installed linux-header, generic did have the
  crtsavres.o file, while it was missing in other case.

  Recreating the issue:

  Again with ' linux-headers-4.2.0-16-generic' HID_module compiled successfully, however failed with ' linux-headers-4.2.0-16' with same error 
  >> 'ld: cannot find arch/powerpc/lib/crtsavres.o: No such file or directory'
