elisp: use suffix rules, get rid of 'elisp-comp' script (mostly a rewrite) Motivated by automake bug#11806. Traditionally, automake byte-compiled emacs-lisp '.el' files by invoking 'elisp-comp' on all of them in a bulk; this involved complex timestamping and file-locking logic. It was also brittle in any slightly-unusual setup, because 'elisp-comp' operated by copying all of the elisp files to be compiled into a temporary sub-directory and compiling them in there, the copying the resulting byte-compile files back in the build directory. This patch removes all of that juggling and chicanery in favour of defining a much simpler '.el.elc' suffix rule. Not only this is simpler, but it also interacts better with "make -jN" calls, which are becoming more and more common and useful on today's increasingly multicore systems. * Makefile.am (dist_script_DATA): Remove 'elisp-comp'. * automake.in (@common_files): Likewise. (handle_emacs_lisp): Do not require 'elisp-comp'. * doc/automake.texi: Remove references to 'elisp-comp'. * lib/am/lisp.am: Define elisp compilation via a suffix rule; this basically amounts to a complete re-write of the lisp byte-compilation rules. * lib/elisp-comp: Remove. * t/add-missing.tap: Remove elisp-comp test. * t/dist-auxdir-many-subdirs.sh: Remove reference to elisp-comp. * t/primary-prefix-invalid-couples.tap: Likewise. * t/primary-prefix-valid-couples.sh: Likewise. * t/lisp4.sh: Remove reference to elc-stamp. * t/lisp5.sh: Likewise. * t/lisp6.sh: Likewise. * t/lisp3.sh: Likewise. Also remove the recompilation check that involves a (message) call. * t/lisp7.sh: Remove check for "Warnings can be ignored". Remove reference to elc-stamp. * t/lisp8.sh: Likewise. * t/lispdry.sh: Remove references to elc-stamp.
