proposed patch for cross compiling from Solaris 2.8

[Jean-Christophe Dubois]

Hello,

I rewrote my patches to be a little more well behaved in regards to non
linux systems.

Any feedback is welcome. Once again this is just to enable Solaris 2.8
(and others?) to be a valid host to cross-compile the 2.6 Linux Kernel
(for PPC).

Regards

JC
