    Fix gensequences for BusyBox awk
    I never thought that I'd have to fix a string concatenation problem in
    a BusyBox awk program to generate VT100 code in a container, but here we
    echo | awk 'END {print "foo" "" ++a, "foo" ++a}'
    should output "foo0 foo1", and for all the ?awk I tested, it does,
    except for BusyBox awk who thought funny to output "0 foo1", breaking the
    teken_state.h file.
