font_acorn_8x8.o was being built in drivers/video/console/ twice during a build _in the same location_ - once for the kernel proper, and once for the decompressor. The result is when you came to run an install target, the kernel was always rebuilt due to this file apparantly having been built with different compiler arguments. Solve this by making a local copy at build time in the decompressor's directory. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
