The only way is to use raw lines for your platform, something like
this for Unix:
OVERRIDES=foo.o
BEGINRAW[Makefile(unix)]
foo.o: foo.c
$(CC) $(CFLAGS) -O3 -c -o $@ $<
ENDRAW[Makefile(unix)]
The reason for this is that as soon as you want to add compiler
specific flags, you also walk away from build.info's general platform
independence. BEGINRAW / ENDRAW is your escape from that
independence.
That being said, I wouldn't recommend mixing object files with and
without debugging information. Configure has the option --debug (-d
to config) to enable debugging, the rest is (hopefully) in the config
target in Configurations/10-main.conf.
Cheers,
