powerpc allyesconfig fix

[Nicholas Krause]

powerpc:allmodconfig has been failing for some time with the following
error.

arch/powerpc/kernel/exceptions-64s.S: Assembler messages:
arch/powerpc/kernel/exceptions-64s.S:1312: Error: attempt to move .org backwards
make[1]: *** [arch/powerpc/kernel/head_64.o] Error 1

A number of attempts to fix the problem by moving around code have been
unsuccessful and resulted in failed builds for some configurations and
the discovery of toolchain bugs.

Fix the problem by disabling RELOCATABLE for COMPILE_TEST builds instead.
While this is less than perfect, it avoids substantial code changes
which would otherwise be necessary just to make COMPILE_TEST builds
happy and might have undesired side effects.

This patch has already bee submitted directly by Guenter, however for
future reference:  when you submit someone else's patch, you should
include a From line as the first line of the email body containing their
email address and you should include a Signed-off-by line from yourself.

Hey Stephen,
Thanks for the heads up on submitting other people's patches. It would
be great if you can push this up into Linus's tree
for the next developer release.

Ben already mentioned that he would pick it up.
