[U-Boot] make Menuconfig Error

Cloned most recent u-boot 2018.06.14 make clean works make menuconfig fails:

/bin/sh: 1: bison: not found scripts/kconfig/Makefile:229: recipe for target 'scripts/kconfig/dochecklxdialog' failed make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1 Makefile:491: recipe for target 'menuconfig' failed make: *** [menuconfig] Error 2

I've checked for bison, visually and with apt-cache search but I have found none.

Will try rebuild based on u-boot from 2018.05.14 on SPDX errors, That version did build.
