Comment (by kencu):

 good news, Iain has added the configuration option we needed, {{{--with-
 darwin-add-path=}}} that allows you to specify a path that the compiler
 will automatically add to the embedded run paths.

 Once we get ready to move to a branch that has this added, we can add this
 to the configure args:

 {{{
 --with-darwin-add-path=${prefix}/lib/libgcc
 }}}

 and we should be in business, if keeping @rpaths is what we are going to
 do.
