you are right, if you call ld directly, -elf2flt can't be used. I don't
think that this is really a problem, because you'll hardly link a BFLT
application with ld directly. I haven't ever seen that since I got one
of the first uCsimms. If you still want to do that, you can use
"gcc -nostdlib -Wl,-elf2flt .." as well.
