It's possible to alter the standard object C flags in the following way:
- CFLAGS_perf.o += '...' - alters CFLAGS for perf.o object
- CFLAGS_gtk += '...' - alters CFLAGS for gtk build object
+ CFLAGS_perf.o += '...' - adds CFLAGS for perf.o object
+ CFLAGS_gtk += '...' - adds CFLAGS for gtk build object
+ CFLAGS_REMOVE_perf.o += '...' - removes CFLAGS for perf.o object
+ CFLAGS_REMOVE_gtk += '...' - removes CFLAGS for gtk build object
This C flags changes has the scope of the Build makefile they are defined in.
