+There are a few different CRIS targets:
+@table @code
+@item cris-axis-aout
+Old target.  Includes a multilib for the @samp{elinux} a.out-based
+target.  No multilibs for newer architecture variants.
+@item cris-axis-elf
+Mainly for monolithic embedded systems.  Includes a multilib for the
+@samp{v10} core used in @samp{ETRAX 100 LX}.
+@item cris-axis-linux-gnu
+A GNU/Linux port for the CRIS architecture, currently targeting
+@samp{ETRAX 100 LX} by default.
+@end table
+
+For @code{cris-axis-aout} and @code{cris-axis-elf} you need binutils 2.11
+or newer.  For @code{cris-axis-linux-gnu} you need binutils 2.12 or newer.
