Build-time testing macros in the interpreted mode

[shahor02]

Hi,

In different PRs build tests we have some root -n -b -l -q -e ".L ${MACRO_FILE}" checks failing.
Digging with @sawenzel we saw that this happens due to some included classes not having dictionaries, e.g. those in the DataFormats/Headers/include/Headers, DPL etc. Since these are templated classes, obligatory creation of dictionaries for them would be too complicated.
Should we instead change the macro's check to a compiled mode in O2/Makefile, as
root -n -b -l -q -e ".L ${MACRO_FILE}+" ?

Cheers,
Ruben

For DPL my goal would be to remove any of those, so that ROOT can parse the header just fine. I am not there yet, but that's on the medium term plan. This is of course orthogonal to running the macros in compiled mode.
