+By default, linker plugins (such as the LTO plugin) are built for the
+host system architecture.  For the case that the linker has a
+different (but run-time compatible) architecture, these flags can be
+specified to build plugins that are compatible to the linker.  For
+example, if you are building GCC for a 64-bit x86_64

+GNU/Linux (@samp{i686-pc-linux-gnu}) linker executable (which is
+executable on the former system), you can configure GCC as follows for
