[oe] [PATCH] boost: corrected atomicity.h include for GCC<4.2

[Przemyslaw Wesolek]

This patch is based on upstream correction spotted in 1.40 version.
They allow to properly compile Boost on both <4.2 and >=4.2 GCC.

With GCC 4.2 some headers were changed (see [1]). This patch uses
appropriate header based on GCC version, so allows compilation on
both versions of GCC API. This change affects boost 1.33 and 1.36.
Upstream version 1.34 has hard-coded change to the new header,
so this patch don't apply.

Applicable to both devel and stable.
