cross gcc for ppc

[Tadashi Ogino]

I'm trying to compile ppc(eabi) program on cygnus GCC on NT BOX.

Usually branch function is compiled to 'bl' instruction but it can go
to +- 24bit address. I want to use 32 bit address.

I found ((longcall)) attribute. It is not mentioned in GCC 2.7.2 so I
think it is Cygnus function. But it doesn't work well.

internal error--unrecognizable insn:
    <omitted>

I found rs6000.md has a bug in this case and I think I can fix them
only for my purpose. But if there exists public patch, I want to apply
it. Does anyone know it?

Thanks.
