There is one remaining regression in travis (well, actually two
identical ones) on vexpress which I am pretty stumped by:


I cannot reproduce that outside of travis (although I am using distro
qemu).  I "bisected" it a few days back by cutting down the travis
config to just those two vexpress platforms and pushing different
stages of this patchset to a test branch.  It seemed to be
'efi_loader: refactor boot device and loaded_image handling' that was
triggering it.  Although that patch (or really any of them) don't
touch anything near printenv.  Possibly it could be a build size issue
with EFI_LOADER getting slightly bigger?  I tried updating travis to
use qemu 2.9.0 (which modulo any possible distro patches should match
what I have when I run locally on fedora 26), but that didn't help.

I'm at a bit of a loss about what to do.. I guess I can have a closer
look and see if we have any distro patches on qemu that look somehow
related.  I don't see how this can possibly be a problem w/ the
efi_loader patchset.  Any suggestions welcome.
