kbuild: remove ARCH_{CPP,A,C}FLAGS
These flags were added by commit 61754c18752f ("kbuild: Allow arch Makefiles to override {cpp,ld,c}flags") to allow ARC to override -O2. We did not see any other usage after all. Now that ARC switched to CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3, there is no more user of these variables. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
