[GAS][ARM] Fix testism for bl local v4t test

["Andre Vieira (lists)" <Andre dot SimoesDiasVieira at arm dot com>]

Hi,

This patch fixes a testism.
I believe this test was never really intended to test for this error
message and
'# stderr' never actually checked it.  This warning is tested elsewhere
and to my
understanding it would have not made any sense here either.

I did some archaeological digging and found that the original patch that
was reviewed on the ml contained a blx-thumb-local.{d,s,l}.
See https://sourceware.org/ml/binutils/2009-03/msg00511.html
The commit itself was missing the .s and .d files, I suspect these fell
through the 'svn add' crack and they help explain why there is a
blx-thumb-local.l to begin with.
I re-added them in this patch and updated due to bitrot.

Is this OK for trunk?
