Nelson Chu f0bae2552d RISC-V: Add i-ext as the implicit extension when e-ext is set.
The linker does not care the default versions of the extensions, since
it does not have the default ISA spec setting.  Therefore, linker won't
insert the implicit extensions for the input objects.  But we used to
insert the i-ext as the explicit extension, even if the e-ext is set.
This causes linker to report "cannot find default versions of the ISA
extension `i'" errors when linking the input objects with e-ext.

This patch fixes the above linker problem, and also remove the confused
riscv_ext_dont_care_version function.  Unless these "dont care" extensions
are set in the input architecture explicitly, otherwise we always insert
them as the implicit ones.  Afterwards, let riscv_arch_str1 surpress them
not to output to the architecture string if their versions are
RISCV_UNKNOWN_VERSION.

    * elfxx-riscv.c (riscv_ext_dont_care_version): Removed.
    (riscv_parse_add_subset): Always add the implicit extensions, even if
    their versions are RISCV_UNKNOWN_VERSION.
    (riscv_parse_std_ext): Delay to add i-ext as the implicit extension
    in the riscv_parse_add_implicit_subsets.  Besides, add g-ext as the
    implicit extension after it has been expanded.
    (riscv_parse_add_implicit_subsets): Updated.

		   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.
