ARC: Override toplevel default -O2 with -O3
commit 97709069214eb75312c14946803b9da4d3814203 upstream.
ARC kernels have historically been built with -O3, despite top level
Makefile defaulting to -O2. This was facilitated by implicitly ordering
of arch makefile include AFTER top level assigned -O2.
An upstream fix to top level a1c48bb160f ("Makefile: Fix unrecognized
cross-compiler command line options") changed the ordering, making ARC
-O3 defunct.
Fix that by NOT relying on any ordering whatsoever and use the proper
arch override facility now present in kbuild (ARCH_*FLAGS)
Depends-on: ("kbuild: Allow arch Makefiles to override {cpp,ld,c}flags")
