These produce warnings in the PowerPC allyesconfig build like this: WARNING: 148 bad relocations c00000000e56510b R_PPC64_UADDR64 .rodata+0x0000000001c72378 c00000000e565126 R_PPC64_UADDR64 .rodata+0x0000000001c723c0 They are not drivers that are used on PowerPC (I assume), so mark them to not be built on PPC64 when CONFIG_RELOCATABLE is enabled.
