proposed patch for cross compiling from Solaris 2.8

[Jean-Christophe Dubois]

Hi,

I got into several issues while trying to cross-compile a Linux 2.6 PPC
kernel from a Solaris 2.8 host (beside getting a valid cross compilation
chain). Mainly some programs compiled on the host are not planned to be
compiled on anything but Linux (The host has to run Linux).

While I understand that it makes more sense to use Linux to (cross)
compile Linux, there are case/companies where this is not (yet) an
option.

So here are few minor modifications (against 2.6.7 from kernel.org) I
had to do to get things going. I guess all of these are not PPC
specific. It just happens I am working with PPC targets.

Regards

JC
