libgloss fix for bfin port

[Jeff Law]

gcc-14 will complain loudly both for calling a function without an 
in-scope prototype or when the in scope prototype differs from the known 
signature.

"main" happens to be one of the functions the compiler knows about.  So 
not only do we need to prototype it, we need to make sure the prototype 
matches what GCC thinks it should be.

This fixes the bfin libgloss port to do the right thing for bfin-elf.

OK for the trunk?
