[Orderfile] Tentative fix for orderfile build on Android

dummy.c was failing to link under the orderfile build due to
undefined references to __cyg_profile_func_enter and
__cyg_profile_func_exit.

This is because the orderfile build enables
-finstrument-functions.

This patch attempts to fix that by explicitly disabling
cygprofile instrumentation for dummy.c
