    dropbear: deterministic selection of system -vs- bundled libtom libs
    
    Dropbear will use system versions of libtommath and libtomcrypt if
    available. To make builds deterministic, add a PACKAGECONFIG option
    to choose system libs or force use of the bundled versions.
    
    Note that currently there are no libtommath or libtomcrypt recipes
    in oe-core, so default to using the bundled versions.
