If a tag file is not removed before it is regenerated, the newly
generated data is appended to the old, which preserves stale data and
makes the tag file grow over time.

Currently, it is no longer possible to use the tags file to jump to
system call function definitions with sys_foo, because the definitions
are obscured by use of the SYSCALL_DEFINE* macros.
This patch adds the appropriate option to ctags to make it see through
the macro. Also, it adds the ENTRY() work already done for Exuberant
to Emacs too.

commit 4f628248a578585472e19e4cba2c604643af8c6c aka "kbuild: reintroduce
ALLSOURCE_ARCHS support for tags/cscope" breaks tags generation for
Kconfig symbols.
Steps to reproduce:
make tags
vi -t PROC_FS
It should jump to 'config PROC_FS' line.

This patch reintroduce the ALLSOURCE_ARCHS support for tags/TAGS/
cscope targets. The Kbuild previously has this feature, but after
moving the targets into scripts/tags.sh, ALLSOURCE_ARCHS disappears.
It's something like this:
$ make ALLSOURCE_ARCHS="x86 mips arm" tags cscope

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
