Fix 'package requirements (atomic_ops) were not met' configure error

(fix commit 3d34335)

* configure.ac [$missing_libatomic_ops] (PKG_CHECK_MODULES):
Pass no-op to action-if-not-found parameter (because the default
action-if-not-found ends the execution with an error in case of the
missing dependency).
