That could be implemented somewhat more generic by using nested variable
expansion:

CC:=$(CC_$(CONFIG_ARCH))

and have Kconfig select the right ARCH value depending on the other
booleans:

config ARCH
     string
     default X86 if ARCH_X86
     default ARM if ARCH_ARM

And the test for "suitable toolchain found" can be generalized by
testing for _some_ value in $(CC) after the assignements happened:

ifeq ($(CC),)
$(error no toolchain for architecture '$(CONFIG_ARCH)' found)
endif
