Thank you for your explanation.
BTW,  I am editing user-config.jam, is it right way to edit project-build.jam? 
I have already embedded Linux install on my target, so I am not building the whole system.
I may need to build an application (cross-compile) and move it to the target (maybe with some library, is it will be difficult to link statically)

Thanks,
Leonid

No. You've downloaded the source code package.

So have following options
1. Build b2 for the host, then edit project-build.jam to build boost
libs for the target. (for ex:
https://www.cnx-software.com/2011/10/03/cross-compiling-boost-c-libraries-for-arm/)
2. Since you've used OE SDK (it's Yocto project I think), enable boost
recipe in OE bitbake to build your SDK with boost libs. Then you'll be
able to use it from SDK sysroot.

The latter option is preferred and more natural for your embedded
target unless you need a bleeding-edge boost version.
