security_flags: Add SECURITY_CFLAGS to TARGET_CC_ARCH for binutils
libtool decides to filter out -fstack-protector-strong on its own and its documented here https://www.gnu.org/software/libtool/manual/html_node/Stripped-link-flags.html this causes linking errors when linking libbfd.so since objects (.o) are compiled using -fstack-protector-strong so they are expecting to link with libssp but the option goes missing in linker flags. With this patch the security flags are hoisted upto CC itself and libtool thankfully does not touch CC. Adding to CC also means that we can now remove it from LDFLAGS since when gcc driver is used to do linking then we have LD = CC and this option makes to linker cmdline Since CC is used without CFLAGS in configure tests, some tests fail complaining that -Olevel is not used while using _FORTIFY_SOURCE therefore added SELECTED_OPTIMIZATION to TARGET_CC_ARCH as well Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
