Remove the need for temacs.in

Instead of building a file temacs.in used only to compute a
fingerprint, compute the fingerprint directly from the .o and
.a files that go into temacs.in.  This speeds up the build by
avoiding the need to link temacs twice, once with a dummy
fingerprint.
* lib-src/make-fingerprint.c (main): No need to generate
a fingerprint file that includes config.h, now that fingerprint.c
depends on all the .o files.
* src/Makefile.in ($(libsrc)/make-fingerprint$(EXEEXT)):
Use the same rule as $(libsrc)/make-docfile$(EXEEXT).
* src/fingerprint-dummy.c: Remove.
* src/Makefile.in (${charsets}, $(libsrc)/make-docfile$(EXEEXT))
($(LIBEGNU_ARCHIVE), $(lwlibdir)/liblw.a, $(oldXMenudir)/libXMenu11.a)
(../config.status, ${ETAGS}, ../lisp/TAGS, $(lwlibdir)/TAGS)
($(lispsource)/loaddefs.el):
Prefer ‘$(MAKE) -C $(dir $@)’ to ‘${MAKE} -C SOMESTRING’ when
either will do, as the former is more regular and lets us
coalesce rules better.
(EMACS_DEPS_PRE, EMACS_DEPS_POST, BUILD_EMACS_PRE)
(BUILD_EMACS_POST, temacs.in$(EXEEXT)): Remove.
(FINGERPRINTED): New macro.
(fingerprint.c): Use it instead of temacs.in$(EXEEXT), to
avoid the need to build temacs.in at all.
(temacs$(EXEEXT)): No need to depend on other .o files now;
fingerprint.o is enough, since it depends on the rest.
Spell out what used to be in BUILD_EMACS_PRE and BUILD_EMACS_POST.
(mostlyclean): No need to remove temacs.in.
