[OE-core] [PATCH] kernel.bbclass: explicitly depend on bison-native for deterministic builds

[Denys Dmytriyenko]

From: Denys Dmytriyenko <denys at ti.com>

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.
