This option is not a gcc option, but a linker option. GCC recognizes
some of the assembler and linker options of the native tools, and
passes them through to those tools. What those options are highly
depends on the platform, and possibly on the exact version of the
assembler and linker.

It is safer to use use the -Wl, option of gcc to pass options to the
linker, that way, there is no confusion with options to other
passes. You'll have to look for the equivalent of -R in your linker
documentation, then.
