Jose E. Marchesi fca8e23c31 ld: use a specific linker script in BPF targets
This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc.  At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)

This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf.  We are not there yet:
BPF "programs" should still be linked with -r.

This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.

Regtested in x86_64 for all targets.
No regressions.

ld/ChangeLog:

2019-08-07  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* scripttempl/elf64bpf.sc: Adapted from elf.sc.
	* emulparams/elf64bpf.sh (SCRIPT_NAME): Use elf64bpf.
	(EMBEDDED): Define.
	* testsuite/ld-bpf/call-1.d: Do not expect a warning regarding an
	undefined entry symbol.
	* testsuite/ld-bpf/jump-1.d: Likewise.
	* testsuite/ld-undefined/undefined.exp: Do not pass '-e entry' to
	ld in BPF targets, and do not expect line number information.
	* testsuite/ld-srec/srec.exp (run_srec_test): xfail s-record tests
	in BPF targets.

README

		   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.
