port elisp-compilation support to emacs-23.1 and newer In May of 2017, emacs.master support for using the long-deprecated byte-compile-dest-file function was removed, and that removal broke automake's elisp-compiling rule for any .el file not in the current directory. In emacs-23.1 (July 2009) byte-compile-dest-file-function became the recommended way to adjust the byte-compiler's destination. The removed functionality has been restored for Emacs-26, albeit with dissuasive diagnostics warning about the imminent removal of this functionality. It will be removed in Emacs-27. * lib/am/lisp.am (.el.elc): Use byte-compile-dest-file-function, rather than byte-compile-dest-file. Also, use "-f batch-byte-compile '$<'" rather than open-coding it, as suggested by Glenn Morris. * t/lisp-readonly-srcdir.sh: New file, to test for the above. * t/list-of-tests.mk (handwritten_TESTS): Add it. * NEWS (Bugs fixed): Mention this problem.
