Add -r option to 6l/8l/5l.
This permits more flexibility with cgo and swig in cases where
the program is run on a machine other than the one on which it
is built. Rather than storing the absolute path to the shared
library in the DT_NEEDED entry, we can store just the name,
and let the dynamic linker find it using DT_RUNPATH or the
LD_LIBRARY_PATH environment variable.
