--- Comment #2 from dhowells at redhat dot com <dhowells at redhat dot com> 2012-11-20 15:09:42 UTC --- The first hunk of the patch that adds: MULTILIB_EXCEPTIONS = *m5-64media* *m5-64media-nofpu* to gcc/config/sh/t-linux causes the sh-linux-gnu build to fail. Commenting out this line allows both sh- and sh64-linux-gnu to build.
