Subject: arc: clean-up and move CFLAGS to include/target.mk
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e620f4d6f83d457579a6ac53d8659f3171739d18;p=openwrt%2Fstaging%2Fneocturne.git

arc: clean-up and move CFLAGS to include/target.mk

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.
