    .....
    There is also one change I have made on the buildsystem. Because I'm using some
    perl inline scripts in the $cmd_xxx the >'< and >$< signs in the inline perl scripts
    cause trouble (perl -e '...$x=....'), the >'< because of the echo command, the >$< when
    rereading from the xxx..cmd files. Could this be applied to the original file?

    scripts/Makefile.lib:
    +-------------------------------+

    # ===========================================================================
    # Generic stuff
    # ===========================================================================

    # function to only execute the passed command if necessary
    # the ' -> '\'' and $ to $$ substitution are done if $(cmd_$(1)) includes a inline perlscript

    if_changed = $(if $(strip $? \
    $(filter-out $(cmd_$(1)),$(cmd_$@))\
    $(filter-out $(cmd_$@),$(cmd_$(1)))),\
    @set -e; \
    $(if $($(quiet)cmd_$(1)),echo ' $(subst ','\'',$($(quiet)cmd_$(1)))';) \
    $(cmd_$(1)); \
    echo 'cmd_$@ := $(subst $$,$$$$,$(subst ','\'',$(cmd_$(1))))' > $(@D)/.$(@F).cmd)
