Explicitly depend on bison-native for deterministic builds, as it is required
for the build:
| HOSTCC scripts/basic/fixdep
| GEN ./Makefile
| HOSTCC scripts/kconfig/conf.o
| YACC scripts/kconfig/zconf.tab.c
| /bin/sh: bison: command not found
| scripts/Makefile.lib:217: recipe for target 'scripts/kconfig/zconf.tab.c'
failed
In most cases, this dependency comes indirectly via toolchain dependencies,
specifically binutils-cross, which pulls bison-native. Different setups,
such as with external toolchain, would expose this problem, since correct
dependency is not marked explicitly.

I'm seeing this now on 4.16-rc2 with external toolchain.
I am not against the addition but in fact, it is because 4.16 stopped
of using pre-generated files and now requires bison to be available.
Ok, good, I was wondering why I didn't see it before 4.16...
I am unsure it ought to be on kernel.bbclass at this moment.
Why not? Because it's 4.16+ specific?
By default bison-native dependency gets added implicitly when built with the
toolchain from oe-core, so this doesn't add any extra dependencies, only makes
it explicit.
it will be overcompensating for < 4.16 kernel recipes where this
dependency is not needed. it might be a legit dependency for another
component, that doesn't stage this package in kernel recipe-specific
sysroot but this change will do that. So its not completely innocent
change.
