Configure gdb for nacl target

gdb/configure.tgt

 # Mappings from configurations to GDB target definitions.  This is
 # invoked from the autoconf generated configure script.
 
 # This file sets the following shell variables:
 #  gdb_target_obs       target-specific object files to use
 #  gdb_sim              simulator library for target
 #  gdb_osabi            default OS ABI to use with target
 #  build_gdbserver      set to "yes" if gdbserver supports target
 
 # NOTE: Every file added to a gdb_target_obs variable for any target here

We need to be more specific here - imagine we want to add nacl gdb for ARM and
other architectures, this case should not fire.

Done.
