What's happened here is that the 'GIT ui/keycodemapdb' checout has not
completed by the time it tries to buil ui/input-keymap-linux-to-qcode.c

Makefile depends on 'git-submodule-update', and Makefile also depends
on $(GENERATED_FILES). IOW the checkout of the git submodules is not
serialized wrt generation of files that use the submodule, and the
patchew test had high enough parallelization to show this flaw, which
my local & Travis tests did not see.

So I need to tweak the deps a little...

Regards,
Daniel
