commit 94796a688d582bfd31b10625e9c0237d7661e393
Author: Maxime Ripard <maxime.ripard at free-electrons.com>

    Fix backslash escaping
    
    Some users have experienced building problems due to the backslash
    escaping not behaving in the same way than on our machine.
    
    Invoking /bin/echo directly fixes that in both cases.
