Let's do it like we do for the ARC architecture: add an option, and the
proper depends on. I.e:

choice
        prompt "Binutils Version"
        default BR2_BINUTILS_VERSION_ARC if BR2_arc
	default BR2_BINUTILS_VERSION_CSKY if BR2_csky
        default BR2_BINUTILS_VERSION_2_31_X
        help
          Select the version of binutils you wish to use.

config BR2_BINUTILS_VERSION_2_30_X
        bool "binutils 2.30"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_2_31_X
        bool "binutils 2.31.1"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_2_32_X
        bool "binutils 2.32"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_ARC
        bool "binutils arc (2.31)"
        depends on BR2_arc

config BR2_BINUTILS_VERSION_CSKY
        bool "binutils csky (2.32)"
        depends on BR2_csky

endchoice

config BR2_BINUTILS_VERSION
        string
	default "c66d8bbcebfddf713b2b436e1b135e6b125a55a5" if BR2_BINUTILS_VERSION_CSKY
        default "arc-2019.03-rc1"       if BR2_BINUTILS_VERSION_ARC
        default "2.30"          if BR2_BINUTILS_VERSION_2_30_X
        default "2.31.1"        if BR2_BINUTILS_VERSION_2_31_X
        default "2.32"          if BR2_BINUTILS_VERSION_2_32_X

Same here, please follow the same logic as the one used for ARC, for
consistency, i.e:

# Version is set when using buildroot toolchain.
# If not, we do like other packages
BINUTILS_VERSION = $(call qstrip,$(BR2_BINUTILS_VERSION))
ifeq ($(BINUTILS_VERSION),)
ifeq ($(BR2_arc),y)
BINUTILS_VERSION = arc-2019.03-rc1
else ifeq ($(BR2_csky),y)
BINUTILS_VERSION = c66d8bbcebfddf713b2b436e1b135e6b125a55a5
else
BINUTILS_VERSION = 2.31.1
endif
endif # BINUTILS_VERSION

ifeq ($(BINUTILS_VERSION),arc-2019.03-rc1)
BINUTILS_SITE = $(call github,foss-for-synopsys-dwc-arc-processors,binutils-gdb,$(BINUTILS_VERSION))
BINUTILS_SOURCE = binutils-gdb-$(BINUTILS_VERSION).tar.gz
BINUTILS_FROM_GIT = y
else ifeq ($(BINUTILS_VERSION),c66d8bbcebfddf713b2b436e1b135e6b125a55a5)
BINUTILS_SITE = $(call github,c-sky,binutils-gdb,$(BINUTILS_VERSION))
BINUTILS_SOURCE = binutils-$(BINUTILS_VERSION).tar.gz
BINUTILS_FROM_GIT = y
endif

What we're doing for ARC is made not the best, but being consistent in
how different architectures do it is much more important.

Thanks,

Thomas
