    kbuild: move .SECONDARY special target to Kbuild.include · 8e9b61b2
    Masahiro Yamada authored
    
    In commit 54a702f7 ("kbuild: mark $(targets) as .SECONDARY and
    remove .PRECIOUS markers"), I missed one important feature of the
    .SECONDARY target:
    
        .SECONDARY with no prerequisites causes all targets to be
        treated as secondary.
    
    ... which agrees with the policy of Kbuild.
    
    Let's move it to scripts/Kbuild.include, with no prerequisites.
    
    Note:
    If an intermediate file is generated by $(call if_changed,...), you
    still need to add it to "targets" so its .*.cmd file is included.
    
    The arm/arm64 crypto files are generated by $(call cmd,shipped),
    so they do not need to be added to "targets", but need to be added
    to "clean-files" so "make clean" can properly clean them away.
