sh-elf stores the 'mach'(ine) information in the elf flags.  We have
no matching mechanism in place for sh-coff.  Hence objdump has no
way to tell what SH variant the code is for.  Note that sh-dsp
/ sh3-dsp use 0xfxxx opcodes for dsp instructions that are used by
the sh3e / sh4 or floating point, so there is no all-encompassing
instruction set that we could use.  We'd have to implement a way
to store the mach value for sh-coff.  That is, if we care about
not having to specify -msh_dsp to objdump when using coff for sh-dsp.
