tags and cscope support really belongs in a shell script
as they do not benefit from the make functionality. Moving the support to a shell script has several benefits: - The readability of the code has increased a lot - More people is able to extend the tags support - We see less changes to the top-level Makefile The shell script version includes improvements from: Alexey Dobriyan <adobriyan@gmail.com> (jump to kconfig symbols) Alexey Dobriyan <adobriyan@gmail.com> (drop ./ in paths) Ian Campbell <ijc@hellion.org.uk> (simplified find algorithms) This version has a few caveats: => It does not support ALLSOURCE_ARCHS - it is easy to add if it is really used => It assumes all archs have moved to arch/$ARCH/include - until that happens we have a few additional hits in the archs Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Alexey Dobriyan <adobriyan@gmail.com> Tested-by: Ian Campbell <ijc@hellion.org.uk>
