kbuild: escape meta characters in regular expression in make TAGS
Alexey Dobriyan <adobriyan@gmail.com> introduced a code adds menuconfig SOMETHING in Kconfig to tags output when you did "make tags". See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=80ff26241623875636674a31c0540a78c0fb5433 "make tags" may work fine with his code. However make TAGS doesn't work well because etags command requires backslashes to escape meta characters like `(', `)' and `|'. Here is a patch.
