ARM: simplify generation of compressed vmlinux.lds file
As we are now using the C preprocessor, we do not need to use sed to edit constants in this file, and then pass the resulting file through the C preprocessor. Instead, rely solely on the C preprocessor to rewrite TEXT_START and BSS_ADDR. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
