crosstool-0.28-rc4 + ppc970 + kernel 2.6.5

[Rafael Ávila de Espíndola <rafael dot espindola at ic dot unicamp dot br>]

I have successfully compiled gcc 3.4 for a ppc970. The attached patch is very 
similar to the one I have send a few weeks ago. There are two significant 
changes:

1) add a "ln -s libgcc.a libgcc_s.a" (cvs libc thinks it needs it)
2) use "--enable-kernel=2.6.5". This is necessary to compile with the headers 
from kernel 2.6.5

What do you thing about using a variable MIN_KERNEL as the parameter to 
--enable-kernel? I.e use --enable-kernel=$MIN_KERNEL.

Thanks.
