buildsys  Check-in [be6fab977d]

Overview
Comment:@rpath is not even needed as install_name

It is possible to set it to the path where the library will be installed
and still have in-tree applications work by setting DYLD_LIBRARY_PATH.
Even if the library is already installed, it will use the in-tree
library if DYLD_LIBRARY_PATH is set.
