Subject: powerpc: select DYNAMIC_DEBUG_RELATIVE_POINTERS for PPC64
Similar to GENERIC_BUG_RELATIVE_POINTERS, one can now relativize the
four const char* members of struct _ddebug, thus saving 16 bytes per
instance (one for each pr_debug(), dev_debug() etc. in a
CONFIG_DYNAMIC_DEBUG kernel). The asm-generic implementation seems to
work out-of-the-box, though this is only compile-tested.
