This option doesn't work correctly on OS X. qbs_disable_rpath should ensure that the install names of shared libraries are $QBS_INSTALL_PREFIX/$QBS_LIBRARY_DIRNAME/libfoo.dylib. Currently, the install name is simply "libfoo.dylib" (relative path).

This breaks the qbs_disable_rpath option for system-level installations like in MacPorts and Homebrew (both of which I'm submitting or submitted qbs to, and it would be preferable to use qbs_disable_rpath for the former since its packages are not designed to be relocatable).
