Basic implementation of 'make headers_install'
This adds a make target which exports a subset of headers which contain definitions which are useful for system libraries and tools. It uses the BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses sed to remove markers like __user. Based on an original implementation by Arnd Bergmann <arnd@arndb.de> Hacked about by David Woodhouse <dwmw2@infradead.org> Reviewed and cleaned up by Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
