"at all", in context.

My copy of the man page defers to -rpath-link for a description of
how -rpath is used at link time; I suspect it's just unclear.

LD searches rpath if USE_LIBPATH.  That is set for native and
sysrooted toolchains only.  Search for command_line.rpath in
emultempl/elf32.em.

I don't know how you have a linker that does otherwise, but
I'd be curious to learn how.
