We surly can. But for some reason no other package under package/ uses
BR2_BISON_HOST_DEPENDENCY. Plain host-bison is used there instead. Only
Barebox, U-Boot and the kernel use it. Why is that?

Commit b01100cc901a83 ("linux: kconfig may need host-{flex, bison} to
build the configurators") mentions kconfig. Is that related?

I guess that BR2_BISON_HOST_DEPENDENCY is more susceptible to
incompatibility due to different host installed bison versions (and same
for flex).
