I'm not sure if this is a bug.

Background:
----------
GDB version 5.2.
Compiled using uclibc like this:
 - configure
 - make
 - cd gdb/gdbserver
 - joe Makefile # so it uses ARM compiler (as specified on
www.uclibc.org)
 - make

The target has an ARM processor and is connected to the i686 host
using Ethernet.


The problem:
------------

The commands:
 - on target: gdbsever host_ip:123 test.arm
 - on host: gdb test.arm, target remote target_ip:123, break main,
continue

The response (on host) is:

warning: Cannot insert breakpoint -3:
Cannot access memory at address 0x207c

By using "set debug remote 1" the following information is obtained:

Why does the target not support those things (symbol-lookup,
software-breakpoint, binary d/l)?
