Mike Frysinger 462d6942f6 newlib: drop i?86-pc-linux-* target support
This was added 20+ years ago.  It seems to have very few (or no users)
as it only works on 32-bit x86 GNU/Linux (i.e. glibc) systems, and even
then only with old versions of glibc.  It hasn't compiled in at least 5
years, but most likely been broken for more like 15 years -- it relies
on internal glibc APIs (like linuxthreads), and that code has changed
and been deleted significantly since.

This single target ends up dragging in a lot of non-trivial code that is
hard to keep working, and currently impossible to verify -- the libtool
and iconvdata and sys/linux/ code isn't used by anything else, but ends
up touching just about every build file in the tree.  Punt the target so
we can start stripping out all these unique code paths.

This commit by itself just disables the target.  We'll start deleting the
individual unused pieces in followups.

		   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
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
