[ Upstream commit 0cfccb3c04934cdef42ae26042139f16e805b5f7 ]

The top-level boot_targets (uImage and uImage.*) should be phony
targets. They just let Kbuild descend into arch/arc/boot/ and create
files there.

If a file exists in the top directory with the same name, the boot
image will not be created.

You can confirm it by the following steps:

$ export CROSS_COMPILE=<your-arc-compiler-prefix>
$ make -s ARCH=arc defconfig all # vmlinux will be built
$ touch uImage.gz
$ make ARCH=arc uImage.gz
CALL scripts/atomic/check-atomics.sh
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
# arch/arc/boot/uImage.gz is not created

Specify the targets as PHONY to fix this.
