section without SHF_EXECINSTR.

moved to Arm_relobj::make_exidx_input_section. Add an assertion to
check that there is no deferred EXIDX section if we exit early.
Instead of not making an EXIDX section in case of an error, make one
and set the has_errors flag of it.

in a relocatable link.
(Target_arm::do_relax): Look for the EXIDX output section instead of
assuming that it is called .ARM.exidx.

section list. Do not check for SHF_EXECINSTR section flags but
skip any input section with errors.

always_keeps_input_sections_.

This is just a copy of the Python 2.7 version of python-config.py.
Tested with versions 2.5 and 2.6. It's nearly identical to the
previous version, except it's written in a more pythonic way,
so it should be fine for 2.4 as well.
gdb/ChangeLog:
* python/python-config.py: Resync with Python 2.7 version of this
script.

This is on GNU/Linux.
GDBserver does not exit properly when the inferior exits, as demonstrated
with any program using the procedure below:
% gdbserver-head :4444 simple_main
Process simple_main created; pid = 25681
Listening on port 4444
Then, in another terminal, start GDB, connect to GDBserver, and run
the program to completion:
% gdb-head simple_main
(gdb) tar rem :4444
(gdb) cont
Continuing.
Program exited normally.
Going back to the terminal where GDBserver is running, we see the following
output:
Child exited with status 0
readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.
Listening on port 4444
The problem is that we're missing a call to mourn_inferior. As a result,
after we've handled the vCont packet, we fail to notice that there are
no process left to debug (target_running() returns true), and thus try
to continue reading from the remote socket. However, since GDB just
disconnected after having received the "exit with status 0" reply to the
vCont request, the read triggers the EOF exception.
gdb/gdbserver/ChangeLog:
* server.c (handle_v_cont): Call mourn_inferior if process
just exited.
(myresume): Likewise.

I just happened to notice that this function was exclusively used in
server.c, and thus could be made static.
