I'm using (something like) ARFLAGS ?= qcsDP.  If I need a
multi-system Makefile, I'll probably have the makefile run some
tests to detect the system and append to ARGFLAGS accordingly;
something like:

ARFLAGS += $(shell ... test weird system ... && echo -Xany)

But I very much prefer knowing what goes into my flags exactly,
and where it comes from.

Alex
