powerpc: Fix build warning on 32-bit PPC
I am getting the following warning when I build kernel 4.9-git on my
PowerBook G4 with a 32-bit PPC processor:
AS arch/powerpc/kernel/misc_32.o
arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]
This problem is evident after commit 989cea5c14be ("kbuild: prevent
lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
error that has been in the code since 2005 when this source file was
created. That was with commit 9994a33865f4 ("powerpc: Introduce
entry_{32,64}.S, misc_{32,64}.S, systbl.S").
The offending line does not make a lot of sense. This error does not
seem to cause any errors in the executable, thus I am not recommending
that it be applied to any stable versions.
Thanks to Nicholas Piggin for suggesting this solution.
Fixes: 9994a33865f4 ("powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S")
