dependency tracking in ld
ld/:
* Makefile.am (AUTOMAKE_OPTIONS): Remove cygnus. Add
no-texinfo.tex, no-dist, foreign.
(TEXINFO_TEX): New variable.
(install-data-local): Removed, not needed any more.
(all): Dependencies upon info and ld.1 not needed any more.
(MKDEP, DEP, DEP1, dep.sed, dep, dep-in, dep-am): Removed.
(mkdep generated section): Removed.
(ldgram.o, ldlex.o, deffilep.o, ldmain.o, ldfile.o): Rewrite to
use automake dependency tracking mechanism.
(EXTRA_ld_new_SOURCES): Add pep-dll.c, pe-dll.c, and
$(ALL_EMULATIONS:.o=.c) $(ALL_64_EMULATIONS:.o=.c) so their
dependencies are tracked too.
(BUILT_SOURCES): New, list $(GENERATED_HFILES) to ensure they
are built early.
* configure.in: Use AM_MAINTAINER_MODE.
* configure, Makefile.in: Regenerate.
