[Boost-build] recursively call unit test executable

hi all,

i'm currently having some trouble with b2: to test lockfree with
interprocess, i'm calling the executable itself:

https://github.com/boostorg/lockfree/blob/master/test/queue_interprocess_test.cpp#L38

`std::system()` isn't able to resolve the dynamic libraries, so it fails
with:
> dyld: Library not loaded: libboost_chrono.dylib
>   Referenced from: /Users/tim/dev/boost/libs/lockfree/test/../../../bin.v2/libs/lockfree/test/queue_interprocess_test.test/darwin-4.2.1/debug/threadapi-pthread/threading-multi/visibility-hidden/queue_interprocess_test
>   Reason: image not found

this seems to be the case because the binaries lack the rpath:

any idea how to make this work?
