Yes, this is exactly what libtool is doing it now. But RPATHs in lt-progname 
for libs which are indirect dependencies (no NEEDED in lt-progname, but 
NEEDED in the lib which is a direct dependant) are overriden by RPATHs in the 
direct-dependant library. Previously this was not a problem, because there 
were no indirect dependencies before, all libraries were NEEDED in 
lt-progname. The dynamic linker falls back to RPATH in lt-progname only if 
the indirect dependency is not found in any RPATH in the direct-dependant 
library.
