Andrew Burgess 361cb21935 gnulib: Ensure all libraries are used when building gdb/gdbserver
An issue was reported here related to building GDB on MinGW:

  https://sourceware.org/pipermail/gdb/2020-September/048927.html

It was suggested here:

  https://sourceware.org/pipermail/gdb/2020-September/048931.html

that the solution might be to make use of $(LIB_GETRANDOM), a variable
defined in the gnulib makefile, when linking GDB.

In fact I think the issue is bigger than just LIB_GETRANDOM.  When
using the script binutils-gdb/gnulib/update-gnulib.sh to reimport
gnulib there is a lot of output from gnulib's gnulib-tool.  Part of
that output is this:

  You may need to use the following makefile variables when linking.
  Use them in <program>_LDADD when linking a program, or
  in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
    $(FREXPL_LIBM)
    $(FREXP_LIBM)
    $(INET_NTOP_LIB)
    $(LIBTHREAD)
    $(LIB_GETLOGIN)
    $(LIB_GETRANDOM)
    $(LIB_HARD_LOCALE)
    $(LIB_MBRTOWC)
    $(LIB_SETLOCALE_NULL)
    $(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise

What I think this is telling us is that we should be including the
value of all these variables on the link line for gdb and gdbserver.

The problem though is that these variables are define in gnulib's
makefile, but are not (necessarily) defined in GDB's makefile.

One solution would be to recreate the checks that gnulib performs in
order to recreate these variables in both gdb's and gdbserver's
makefile.  Though this shouldn't be too hard, most (if not all) of
these checks are in the form macros defined in m4 files in the gnulib
tree, so we could just reference these as needed.  However, in this
commit I propose a different solution.

Currently, in the top level makefile, we give gdb and gdbserver a
dependency on gnulib.  Once gnulib has finished building gdb and
gdbserver can start, these projects then have a hard coded (relative)
path to the compiled gnulib library in their makefiles.

In this commit I extend the gnulib configure script to install a new
makefile fragment in the gnulib build directory.  This new file will
have the usual variable substitutions applied to it, and so can
include the complete list (see above) of all the extra libraries that
are needed when linking against gnulib.

In fact the new makefile fragment defines three variables, these are:

LIBGNU: The path to the archive containing gnulib.  Can be used as a
       dependency as when this file changes gdb/gdbserver should be
       relinked.

LIBGNU_EXTRA_LIBS: A list of linker -l.... flags that should be
       included in the link line of gdb/gdbserver.  These are
       libraries that $(LIBGNU) depends on.  This list is taken from
       the output of gnulib-tool, which is run by our
       gnulib/update-gnulib.sh script.

INCGNU: A list of -I.... include paths that should be passed to the
       compiler, these are where the gnulib headers can be found.

Now both gdb and gdbserver can include the makefile fragment and make
use of these variables.

The makefile fragment relies on the variable GNULIB_BUILDDIR being
defined.  This is checked for in the fragment, and was already defined
in the makefiles of gdb and gdbserver.

gdb/ChangeLog:

	* Makefile.in: Include Makefile.gnulib.inc.  Don't define LIBGNU
	or INCGNU.  Make use of LIBGNU_EXTRA_LIBS when linking.

gdbserver/ChangeLog:

	* Makefile.in: Include Makefile.gnulib.inc.  Don't define LIBGNU
	or INCGNU.  Make use of LIBGNU_EXTRA_LIBS when linking.

gnulib/ChangeLog:

	* Makefile.gnulib.inc.in: New file.
	* Makefile.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Install the new file.
