Subject: [PATCH] admin/unidata: small Makefile simplifications

* admin/unidata/Makefile.in (${top_srcdir}/src/macuvs.h): Make and load .elc.
(.el.elc): Replace with pattern rule.
(%.elc): New.
(unidata.txt): Use $<.
(compile): Remove.
(${DSTDIR}/charprop.el): Use order-only prereqs rather than a sub-make.
