We don't need to explicitly invoke the archheaders target because of
the dependency on __headers in the Makefile.

Add support for an "archheaders" target.  This target can generate
files that need to be installed for user space by "make
headers_install" or "make headers_install_all".

In order to support "make headers_install_all", it must be able to run
without the tree having to be configured first.

Using HDR_ARCH_LIST you can specify subset of architectures you want to get
headers for.

No architectures uses include/asm-$ARCH now.
So drop check for location of include files

'drop' variable is unused.

'ppc' and 'sparc64' directories don't exist in arch/,
and I think their headers can be well exported now, so
just remove them.

Factor out the headers_*_all support to a seperate
shell script and add support for arch specific
header files can be located in either

    arch/$ARCH/include/asm
or
    include/asm-$ARCH/

In "make help" always display the headers_* targets.
