`make tags` fixes (GH-717)
* Fix `make tags` warnings
`make tags` target tries to find C sources and headers in "Grammar" and
"Mac" folders and generates these warnings:
ctags: Warning: cannot open source file "Grammar/*.[ch]" : No such file or directory
ctags: Warning: cannot open source file "Mac/*.[ch]" : No such file or directory
This commit changes $SRCDIRS variable in configure.ac to remote these
directories. This variable is used only for tags generation.
Also, "configure" was regenerated with `autoreconf`.
* Fix `make tags` fail on non-default tag names
When ctags overrides default tags filename (e.g. `-f .tags`) `make tags`
is failed because it assumes to see default `tags` filename:
sort: cannot read: tags: No such file or directory
This commit explicitly specifies "tags" filename for tags generation.
