hardcoded compilation flags

[GoogleCodeExporter]

Hello,

One could want to override default compilation flags:
mman.o: mman.c mman.h
        $(CC) -o mman.o -c mman.c -Wall -O3 -fomit-frame-pointer

Maybe a CFLAGS var could be added at the top of the Makefile:
CFLAGS=-Wall -O3 -fomit-frame-pointer

Then rewrite the rule:
mman.o: mman.c mman.h
        $(CC) $(CFLAGS) -o mman.o -c mman.c
