[OE-core] 64-bit gcc hack patch /

[Kumar Gala]

What is meta/recipes-devtools/gcc/gcc-4.6/64bithack.patch really accomplishing at this point?

Its not clear to me what benefit or what is really impacted by the following change:

 MULTILIB_OPTIONS = m64/m32
-MULTILIB_DIRNAMES = 64 32 
-MULTILIB_OSDIRNAMES = ../lib64 $(if $(wildcard $(shell echo $(SYSTEM_HEADER_DIR))/../../usr/lib32),../lib32,../lib)
+MULTILIB_DIRNAMES = . 32
+MULTILIB_OSDIRNAMES = . $(if $(wildcard $(shell echo $(SYSTEM_HEADER_DIR))/../../usr/lib32),../lib32,../lib)

Trying to decide if the ppc equivalent of this patch is really needed or not.
