    base.bbclass: extend PACKAGECONFIG to also allow RRECOMMENDS
    
    It can be useful to add RRECOMMENDS to packages created, based
    on certain PACKAGECONFIGs.
    
    In particular where a package depends on certain linux kernel
    infrastructure (kernel modules) which might or might not be
    built as a module, being able to RRECOMMENDS instead of
    RDEPENDS on the relevant packages avoids build failures in
    case those modules are built statically into the kernel, i.e.
    in case no package is being created for them.
    
    Add another field to the PACKAGECONFIG syntax to achieve just
    that.
