 I'm not so sure about this one. _EXTRA_DOWNLOADS is currently used for the
blackfin toolchains and for perl. Toolchains are target packages so no issue
there, but for perl, we really only need perl-cross for the target perl. At the
moment, host-perl is only built as a dependency of perl so it doesn't hurt to
download perl-cross for host-perl, but it is unnecessary.

 Is there a hidden reason why you want this (i.e. is it required for some later
patch)?
