Thanks applied. I made some small changes though:

    [Thomas:
     - add HOST_OLA_DEPENDENCIES variable, so that host-ola doesn't get
       all the dependencies of the target ola package: certain target
    ola dependencies do not have corresponding host packages (and it
       doesn't make sense to have them as dependencies just to build
       ola_protoc)
     - improve the commit log to mention which upstream commits
    correspond to our patches.]

Of course, the first change is the most important one: if you were
enabling all of the Ola sub-options, it would no longer build due to
host-ola depending on non-existing host packages (because when the
dependencies of a host package are not explicitly given, they are
inherited from  the dependencies of the corresponding target package).

Thanks!
