kbuild: add "Section mismatch" warning whitelist for powerpc
This patch fixes the following class of "Section mismatch" warnings when building powerpc platforms. WARNING: arch/powerpc/kernel/built-in.o - Section mismatch: reference to .init.data:.got2 from prom_entry (offset 0x0) WARNING: arch/powerpc/platforms/built-in.o - Section mismatch: reference to .init.text:mpc8313_rdb_probe from .machine.desc after 'mach_mpc8313_rdb' (at offset 0x4) ....
