Joel Brobecker 648d586d84 configure gdb/gnulib with --disable-largefile if largefile support disabled.
This patch mostly aims at fixing a GDB build failure on 32bit Solaris
systems (Sparc and x86), due to a recent gnulib update adding the
readlink module. But it might also fix related issues when configuring
with --disable-largefile.

A side-effect of the gnulib readlink module addition is that it caused
largefile support to be added as well, and in particular
gnulib/import/m4/largefile.m4 introduced the following new #define in
gnulib's config.in:

| +/* Number of bits in a file offset, on hosts where this is settable. */
| +#undef _FILE_OFFSET_BITS

When defined to 64, it triggers an issue with procfs.h while trying
to build sparc-sol2-nat.c:

| #if !defined(_LP64) && _FILE_OFFSET_BITS == 64
| #error  "Cannot use procfs in the large file compilation environment"
| #endif

As it turns out, this is a fairly familiar problem, and one of
the reasons behind ACX_LARGEFILE having been created. In that macro,
we have some code which disables largefile support on solaris hosts:

|   sparc-*-solaris*|i[3-7]86-*-solaris*)
| changequote([,])dnl
|     # On native 32bit sparc and ia32 solaris, large-file and procfs support
|     # are mutually exclusive; and without procfs support, the bfd/ elf module
|     # cannot provide certain routines such as elfcore_write_prpsinfo
|     # or elfcore_write_prstatus.  So unless the user explicitly requested
|     # large-file support through the --enable-largefile switch, disable
|     # large-file support in favor of procfs support.
|     test "${target}" = "${host}" -a "x$plugins" = xno \
|       && : ${enable_largefile="no"}
|     ;;

But gnulib ignores this fact, and so tries to determine how to
enable large-file support irrespective of whether we want it or not.
This patch fixes the issue by passing --disable-largefile to gnulib's
configure when large-file support in GDB is disabled. This is done
by first enhancing ACX_CONFIGURE_DIR to allow us to pass extra
arguments to be passed to the configure command, and then by modifying
GDB's configure to pass --disable-largefile if large-file support
is disabled.

gdb/ChangeLog:

	* acx_configure_dir.m4 (ACX_CONFIGURE_DIR): Add support for
        new "EXTRA-ARGS" parameter.
	* configure.ac: If large-file support is disabled in GDB,
        pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
	* configure: Regenerate.

gdb/gdbserver/ChangeLog:

	* configure.ac: If large-file support is disabled in GDBserver,
        pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
        * configure: Regenerate.

Tested by rebuilding on sparc-solaris and x86_64-linux (with gdbserver).
This fixes the build failure on sparc-solaris. I also verified in
gnulib's config.log file that we pass --disable-largefile in the solaris
case, while we do not in the GNU/Linux case.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
