Issues with devel/boost-* on Sparc64

[Alexander Churanov]

Folks,

I've identified the root cause of the issue.
Boost folks are using custom routine written in assembly language for SPARC.

If the line 57 of boost/smart_ptr/detail/sp_counted_base.hpp is
commented, the implementation switches to spin-locked and code
compiles successfully.

I will contact Boost developers in order to fix this in upstream.
I'll also create a patch for devel/boost-libs port for using in the meanwhile.
