[ELDK] PPC_6xx does not have brlock.h

Hi Douglas,

It shouldn't have been a problem to say that you are trying to do
userspace _and_ kernel devleopment.

If you link against kernel code, you really need to be GPL compatible,
so I wonder how long you can keep "your rules", but that's something you
need to take care of.

At least I know that you are not only doing userspace development.  In
this case I suggest strongly that you disregard the kernel contained
in the ELDK and use the kernel that you need for your "application".

Note however that the precompiled binaries in the ELDK are compiled
against the contained kernel version, so if you deviate too much from
that, you will surely run into trouble.  I.e. using a 2.4 kernel with
ELDK 4.x will only work by pure chance.  ELDK 3.2 was the last version
running in conjunction with a 2.4 kernel.

Moreover if the code you try to compile uses a linux header file which
seems to be gone for a long time, I would not be surprised if you need
to spend a significant amount of time to get it running on a current
kernel.  But then again, maybe you are lucky.

Best wishes
  Detlev
