Re: SH -ml not turning into -EL to ld

[Joel Sherrill <joel dot sherrill at oarcorp dot com>]

Following up to myself... I don't know exactly how to fix
this but I think I have pulled the right thread.

gcc/config/sh/superh.h defined SUBTARGET_LINK_SPEC which
appears to have the right arguments.

sh-rtems4.11-gcc -dumpspecs shows that *link ends with
"%(subtarget_link_spec} which seems correct. But that is
defined to nothing when I think it should be
"%{ml:-EL}%{mb|!ml:-EB}"

configure.gcc shows that sh-superh-elf includes these which
are not in the sh-rtems*) target:

                       tm_file="${tm_file} sh/superh.h"
                        extra_options="${extra_options} sh/superh.opt" ;;


Do we need to add those? Anything else we might be missing?
