ARM: 7420/1: Improve build environment isolation
Increasingly distributions are setting default build environments to have LDFLAGS with hardening options. There seems to be an assumption with those options that LDFLAGS are passed to the compiler frontend rather than used directly with ld (which the kernel build process assumes) To prevent build failures in such environments this patch changes the ARM architecture Makefile to override the LDFLAGS from the environment similar to the behaviour on other common architectures e.g. x86 Signed-off-by: Vincent Sanders <vince@collabora.co.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
