xtensa: add boot subdirectories build artifacts to 'targets'

Xtensa always rebuilds the following even if nothing in the source code
has been changed. Passing V=2 shows the reason.

AS arch/xtensa/boot/boot-elf/bootstrap.o - due to bootstrap.o not in $(targets)
LDS arch/xtensa/boot/boot-elf/boot.lds - due to boot.lds not in $(targets)

They are built by if_changed(_dep). Add them to 'targets' so .*.cmd files
are included.

xtensa: clean up bootable image build targets

Currently xtensa uses 'zImage' as a synonym of 'all', but in fact xtensa
supports three targets: 'Image' (ELF image with reset vector), 'zImage'
(compressed redboot image) and 'uImage' (U-Boot image).
Provide separate 'Image', 'zImage' and 'uImage' make targets that only
build corresponding image type. Make 'all' build all images appropriate
for a platform.

When building with binutils-2.18, vmlinux includes .note.gnu.build-id

The old .xt.insn sections haven't been used for a long time, so don't
bother stripping them.

kbuild: enable 'make CFLAGS=...' to add additional options to CC

The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.

One usecase is when trying to find gcc bugs but other
use cases has been requested too.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k

Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.
