Blackfin: More CPU types

This is another one of Jie's patches; this one just completes the
previous -mcpu patch by adding more CPU types.

+Specifies the name of the target Blackfin processor. Currently, @var{cpu}
+can be one of @samp{bf531}, @samp{bf532}, @samp{bf533},
+@samp{bf534}, @samp{bf536}, @samp{bf537}, @samp{bf561}.

+BSP provided by libgloss to be linked in if @samp{-msim} is not given.
+Support for @samp{bf561} is incomplete; only the processor macro is defined.
