[Buildroot] [PATCH 2/2] package/ltp-testsuite: disable for sparc

[Romain Naour <romain.naour@gmail.com>]

As stated in commit [1], sparc toolchains doesn't have
any of __sync_*() family of functions implementation.

When __sync_add_and_fetch() is missing, ltp fallback to a local
implementation of tst_atomic_add_return() specific for each
supported architecture.
But there is none for sparc.

Fixes:
