Library search paths using the -R option

There are multitudes of articles online that proclaim in strident tones that the use of LD_LIBRARY_PATH is a bad idea, and that one must set library search paths using the -R option.

$ readelf -a t|grep RPATH
 0x000000000000000f (RPATH)              Library rpath: [/my/lib/dir]
