Most of currently mentioned CFLAGS in arc770/Makefile
are not really required because:
[1] "-Os -pipe" are set by default in include/target.mk
[2] "-fno-caller-saves" gets enabled via menuconfig
as an extra compiler flag for developers
So the only one that makes sense is "-matomic" and
that one is really essential. Without it many software
packges won't build complainin on unresolved atomic ops.
