I think this test should have a $(call qstrip) to be effective.

It should also be changed in toolchain/gcc/gcc-uclibc-4.x.mk in a
similar way. Code is currently:

ifneq ($(call qstrip,$(BR2_GCC_TARGET_CPU)),)
GCC_WITH_CPU:=--with-cpu=$(BR2_GCC_TARGET_CPU)
endif

It should be:

ifneq ($(call qstrip,$(BR2_GCC_TARGET_CPU)),)
ifneq ($(call qstrip,$(BR2_GCC_TARGET_CPU_REVISION)),)
GCC_WITH_CPU:=--with-cpu=$(call qstrip,$(BR2_GCC_TARGET_CPU)-$(BR2_GCC_TARGET_CPU_REVISION))
else
GCC_WITH_CPU:=--with-cpu=$(call qstrip,$(BR2_GCC_TARGET_CPU))
endif
endif

Once this is one, I think the patch is OK.
