[PATCH, libstdc++/testsuite] 29_atomics/atomic/65913.cc: require atomic-builtins rather than specific target

[Thomas Preudhomme]

[Sorry for the large recipient list, I wasn't sure who of C++ and x86 
maintainers should approve this]

Hi,

29_atomics/atomic/65913.cc test in libstdc++ is a runtime test that only rely 
on atomic and gnu++11 support. Therefore I propose to require atomic-builtins 
instead of an x86 (32 or 64 bits) target.

ChangeLog entry is as follows:

2016-05-19  Thomas Preud'homme  <thomas.preudho...@arm.com>

        * testsuite/29_atomics/atomic/65913.cc: Require atomic-builtins rather
        than specific target.


Patch is in attachment.


Is this ok for trunk?

Best regards,

Thomas
