This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot. ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * MAINTAINERS: Add gnulib. * gnulib: New directory, move from gdb/gnulib. * configure.ac (host_libs): Add gnulib. * configure: Rebuild. * Makefile.def (host_modules, dependencies): Add gnulib. * Makefile.in: Rebuild. gdb/ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * gnulib: Move directory to top-level. * configure.ac: Don't configure gnulib. * configure: Rebuild. * common/common-defs.h: Use new path to gnulib. * Makefile.in (GNULIB_BUILDDIR): Now ../gnulib. (GNULIB_H): Remove. (INCGNU): Look in new gnulib location. (HFILES_NO_SRCDIR): Remove gnulib files. (SUBDIR, REQUIRED_SUBDIRS): Remove gnulib. (generated_files): Remove GNULIB_H. ($(LIBGNU), all-lib): Remove targets. (distclean): Don't mention GNULIB_BUILDDIR.
