The way to do this is to call process_multilib_options with the
appropriate options ie:

process_multilib_options "-EL -msoft-float"

You would do this in the baseboards/blah.exp file.  You might also need
to set run_multiple_targets 1.  Not sure about that.

I suspect you're getting baseboards/unix.exp by default, you can either
put it in there (a hack, but effective if you don't care about other
targets).

Or you can create a site.exp, which does something like this:

# Needed for isnative.
load_lib "framework.exp"

# Make sure we look in the right place for the board description files.
if ![info exists boards_dir] {
    set boards_dir {}
}

#
# If we're testing GCC, G++ or GDB, then we want to run on all the
# available targets. Otherwise, just test the first one.
#
if ![info exists tool] {
    set run_multiple_targets 0;
} elseif { $tool == "g++" || $tool == "gcc" || $tool == "gdb" || $tool == "libg++" || $tool == "libstdc++" || $tool == "libio" || $tool == "binutils" } {
    set run_multiple_targets 1;
} else {
    set run_multiple_targets 0;
}


verbose "Global Config File: target_triplet is $target_triplet" 2
global target_list
case "$target_triplet" in {
    { "native" } {
        set target_list "unix"
    }
}


You'd create another entry in the switch for sco5, which would set the
target list to something like sco5.

baseboards/sco5.exp would look like unix.exp, except for the
process_multilib_options line.

Oh yea, you need to tell dejagnu about site.exp.  I think the proper
way is to set the environment variable DEJAGNU to whatever site.exp
you want to use.

Phew...
