This changes gdbserver so that it no longer builds its own gnulib and libiberty. Instead, it now relies on the ones that were already built at the top level. gdbsupport is still built specially for gdbserver. This is more complicated and will be tackled in a subsequent patch. ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def: Make gdbserver require gnulib and libiberty. gdbserver/ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * acinclude.m4: Don't include acx_configure_dir.m4. * Makefile.in (LIBIBERTY_BUILDDIR, GNULIB_BUILDDIR): Update. (SUBDIRS, CLEANDIRS, REQUIRED_SUBDIRS): Remove. (all, install-only, uninstall, clean-info, clean) (maintainer-clean): Don't recurse. (subdir_do, all-lib): Remove. ($(LIBGNU) $(LIBIBERTY) $(GNULIB_H)): Remove rule. (GNULIB_H): Remove. (generated_files): Update. ($(GNULIB_BUILDDIR)/Makefile): Remove rule. * configure: Rebuild. * configure.ac: Don't configure gnulib or libiberty. (GNULIB): Update. gdbsupport/ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * common-defs.h: Change path to gnulib/config.h. Change-Id: I469cbbf5db2ab37109c058e9e3a1e4f4dabdfc98
