[PATCH][ARM][tests] Add -march=armv6 to tests that have -mapcs

[Kyrill Tkachov]

Hi all,

I'm proposing a gas patch to add warnings for deprecated forms of ldm in 
ARMv7-A.
(https://sourceware.org/ml/binutils/2015-01/msg00158.html)
Unfortunately, GCC generates these deprecated forms with -mapcs-frame.
Since the deprecation happens only from armv7-a onwards, this patch adds 
-march=armv6 to the tests that use -mapcs so that the assembler doesn't 
complain. -mapcs is a pretty old option that was not intended to be used 
with newer architecture levels anyway, as far as I can tell.

Ok for trunk?

Thanks,
Kyrill
