    kbuild: introduce ccflags-y, asflags-y and ldflags-y

    Introduce ccflags-y, asflags-y and ldflags-y so we soon can
    deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS.
    This patch does not touch any in-tree users - thats next round.
    Lets get this committed first and then fix the users of the
    soon to be deprecated variants next.

    The rationale behind this change is to introduce support for
    makefile fragments like:

    ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG

    As a replacement for the uglier:
    ifeq ($(CONFIG_WHATEVER_DEBUG),y)
            EXTRA_CFLAGS := -DDEBUG
    endif

This makes 2 big problems with this patch in the last 1 hour.

Probably time to revert it...

Subject: [PATCH] x86: fix boot error introduced by kbuild

x86 uses target specific assignment of EXTRA_AFLAGS,
EXTRA_CFLAGS - this caused troubles with
introducing asflags-y, ccflags-y.

Fixed the target specific assignments in arch/x86/boot/Makefile
and auditted the rest of the kernel for similar usage.
