Remove duplicated include file

File x86-linux-nat.h is included twice in amd64-linux-nat.c and
i386-linux-nat.c.  This patch is to remove one.

Rearrange awkwardly-nested conditionals

gdbserver's init_register_cache has some preprocessor conditionals
awkwardly nested around an if..else block.  This commit moves the
conditionals inside the braces to make the code more readable.

Rename variable with confusing name

I saw this gem of not so legible code in solib-svr4.c (scan_dyntag):

	if (dyn_tag == dyntag)

and thought it deserved a small rename.

This just renames variables to be a bit more clear for those who read the
code. I also constified the parameter because, why not. The same was
done in scan_dyntag_auxv as well.

Tested only by rebuilding, since the change was done mechanically.

gdb/Changelog:

2014-08-01  Simon Marchi  <simon.marchi@ericsson.com>

	* solib-svr4.c (scan_dyntag): Rename dyntag and dyn_tag variables.
	(scan_dyntag_auxv): Same.

Merge WARN and CWARN cases in _bfd_generic_link_add_one_symbol

WARN has always been able to be handled by the CWARN case (WARN was
used when the previous symbols was undef, undefweak or common and thus
must be on the undefs list, so the CWARN test passes).  So let's merge
those two cases.

	* linker.c (WARN, CWARN): Collapse these states to WARN.
	(_bfd_generic_link_add_one_symbol): Use old CWARN case for
	new WARN.
