kbuild: remove headers_{install,check}_all

Browse Source 
headers_install_all does not make much sense any more because different
architectures export different set of uapi/linux/ headers. As you see
in include/uapi/linux/Kbuild, the installation of a.out.h, kvm.h, and
kvm_para.h is arch-dependent. So, headers_install_all repeats the
installation/removal of them.

If somebody really thinks it is useful to do headers_install for all
architectures, it would be possible by small shell-scripting, but
the top Makefile does not have to provide entry targets just for that
purpose.

An 'include' directory is automatically created inside INSTALL_HDR_PATH and
headers are installed in 'INSTALL_HDR_PATH/include'.
The command "make headers_install_all" exports headers for all architectures
simultaneously. (This is mostly of interest to distribution maintainers,
who create an architecture-independent tarball from the resulting include
directory.) You also can use HDR_ARCH_LIST to specify list of architectures.
Remember to provide the appropriate linux/asm directory via "mv" or "ln -s"
before building a C library with headers exported this way.
The kernel header export infrastructure is maintained by David Woodhouse
<dwmw2@infradead.org>.
