I just "sudo apt-get install flex bison" and it worked great.

Not so much for me:
Debian, with flex ncurses5-dev and bison++
root at debian:/home/duncan/archive/u-boot# make clean
root at debian:/home/duncan/archive/u-boot# make menuconfig

Raspbian no flex :-(

pi at raspberrypi:~/server/archive/u-boot $ sudo apt install flex

Package flex is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'flex' has no installation candidate

In this repository. It might exist elsewhere.

I generally use raspbian to compile u-boot for the raspberry pi, and Debian as a file server.

The 06.15.2018 version works.
Instead of installing bits and pieces of the toolchain, how about reverting to the previous  version?
Is there link to updated documentation for pre-regs?
