This define_insn looks wrong. There are no operand predicates. There
are no operand constraints. A define_expand does not need those; a
define_insn does.

If you look carefully at the make log, you will see the compilation
command that is being run. Run that command with the --save-temps
option. Look at the resulting libgcc2.s file. Make sure the blt
instructions looks right.
I assume that you have tested your assembler to confirm that it
handles blt as you want it to.
