it depends on the Makefile, not on gcc. gcc knows nothing about
LDFLAGS. and you're not using make in any of the examples above.

i believe that in general, the use of -rpath as a linker option is
deprecated by most people. it will produce a binary that may do
undesirable things on some systems. its preferred to make the
"executable" a shell script that sets LD_LIBRARY_PATH and then execs
the "real" (binary) executable.
