Sergio Durigan Junior 7a6dbc2fdb Update gnulib to current upstream master
It has been a while since we don't update our gnulib copy against
their upstream master branch, so I thought I'd propose this patch.  It
also fixes (at least) one bug reported against GDB:

  https://sourceware.org/bugzilla/show_bug.cgi?id=23558

The problem reported there is about the replacement of 'getcwd' when
cross-compiling GDB.  With our current gnulib copy, the mechanism for
deciding whether to use the system's 'getcwd' or gnulib's version is
too simplistic and pessimistic, so when cross-compiling we always end
up using gnulib's version, which has a limitation: it cannot handle
the situation when the parent directory doesn't have read permissions.

This has been reported against upstream gnulib and the fix has been
pushed here:

  https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=a96d2e67052c879b1bcc5bc461722beac75fc372

I regtested this patch on Fedora 28 x86-64, and there were no
regressions.

OK?

		   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
