boost.serialization compile problem on Android

[Berkus <berkus@…>]

Hello, in attempt to build boost for android with more or less reasonable strict settings (-Werror) I uncovered some bugs which I cannot report on github because these projects have Issues disabled.

This is using clang toolchain on Android NDK r16 beta1.

​Reference to user-config.jam for the build
