Presumably it is happy with -Wl,-rpath though? We may need to make the definitions of SHLIB_RPATH_OPT etc in the configure script dependent on the C compiler type on the affected platforms.

Yes, all of these work. The linker is GNU ld.

-Wl,-R
-Wl,-rpath
-rpath

so we can probably just remove lines in configure.ac that force "-R" for FreeBSD.

Yep, that would work for GCC as well. I assume you have a FreeBSD system set up to test this on?
