"install" moves specified targets to a specified location, and does not
care about --prefix options, and about anything user specifies on the command 
line.

The "boost-install" rule will allow user to invoke "bjam install" and "bjam 
stage" with exactly the same arguments that are allowed at top-level, like 
--prefix, or --layout. With "bjam install" both library and headers will be 
installed.

Essentially, "bjam install" in lib dir will be equivalent to

cd $boost_root
bjam install --with-<the-library>
