[oe] [zeus 07/11] grpc: Link with libatomic on clang/x86

[Armin Kuster]

From: Khem Raj <raj.khem at gmail.com>

clang does delegate the atomic<double> calls to libatomic on x86 where
as gcc tries to use intrinsics, its debatable who is right, but it does
seem that clang is safe in case pointer is unaligned
