Re: [Merge] ~bhill/epics-base:shared-rpath-independent-of-static-build into epics-base:7.0

Mark, if you want to understand what flags were used to build a binary, then the output of 'readelf' is quite helpful.  eg. the RUNPATH entry shows the -rpath which was passed to the linker, and the NEEDED entries are the direct library dependencies (the -l passed to the linker).

$ readelf -d bin/linux-x86_64/caget |head

Dynamic section at offset 0x8d90 contains 32 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libca.so.4.13.3]
