Yes, but ccache then just becomes a NOOP - E.G:

./output/host/usr/bin/ccache ./output/host/usr/bin/arm-linux-objdump -v
GNU objdump (GNU Binutils) 2.21.1

We do the same for E.G. the Linux kernel and other packages using
CROSS_COMPILE:

git grep 'CCACHE.*TARGET_CROSS'
boot/barebox/barebox.mk:BAREBOX_MAKE_FLAGS = ARCH=$(BAREBOX_ARCH) CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)"
boot/boot-wrapper-aarch64/boot-wrapper-aarch64.mk:              CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" \
boot/uboot/uboot.mk:    CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" \
linux/linux.mk: CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" \
package/freescale-imx/imx-lib/imx-lib.mk:       CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" \
package/libebml/libebml.mk:     $(MAKE) -C $(@D)/make/linux CROSS="$(CCACHE) $(TARGET_CROSS)"
package/libmatroska/libmatroska.mk:     $(MAKE) -C $(@D)/make/linux CROSS="$(CCACHE) $(TARGET_CROSS)"
