Well, it looks like too much because I have 18.04, too, and I can build.
I cannot say that Ubuntu users cannot build u-boot anymore.
I guess you have /bin/sh -> dash, and /bin/sh -> bash solves the
problem, too. Or using update-alternatives, as we are in Ubuntu. I can
imagine it is disturbing in docker because a further step in
docker-compose to set up the shell is required, too.
As far as I know, default is dash (but was not dash default a long of
time ago ? I wonder this has become an issue recently, I have missed
something in the between). Nevertheless, I am still missing why this is
so important to push here when the user can set the shell and build
without issues. And travis works, too, it is also based on Ubuntu :
trusty, quite old, but I was convinced that dash was the default in
Ubuntu since a long time.

Maybe I am missing the point here...(to be honest: I put the patch in
"Changes requested" a lot of time ago and I have forgotten about it..)
