This option makes ld use DT_RUNPATH instead of DT_RPATH. DT_RPATH is generally considered bad because it takes precedence over LD_LIBRARY_PATH. For example, eog is linked with -rpath /usr/lib/eog, and with DT_RPATH if an old eog is already installed we are basically impossible to debug a new eog build w/o overwriting the system installation first or explicitly using "ld.so --inhibit-rpath" to invoke it. This "new" actually means "new in 2000," it's 24 years ago and all other distros has enabled it. Thus I guess some unexplainable "test suite uses installed library instead of the just built one" issues in BLFS are actually caused by this difference: the package author just assumes everyone is using DT_RUNPATH thus they just set LD_LIBRARY_PATH and consider it enough to test with the just built libraries, but DT_RPATH breaks this expectation. Let's eliminate the difference as it seems not doing anything good and doing so just takes one switch.
