RPMs are not created automatically with `make`, one must manually invoke `make
<da><algo>da.rpm` to trigger the build. This saves some time as RPM generation
is expensive.

* Created individual targets for `<da><algo>da.rpm`
* Created meta target `daqDA-all-rpm` that creates all RPMs (note: it has to be
  invoked in single-core mode to avoid `rpmbuild` problems)
* Only generated RPMs will be copied to `<install_prefix>/darpms`
