RPM dependencies seem to be messed up

Brief summary of issue

Since the dependencies change I've introduced have been reverted, now when trying to install a following problem appears

...

 You could try using --skip-broken to work around the problem

Types of issue

[x] Bug report (report an issue with the code)
[ ] Feature request (request for change which adds functionality)

Expected Behavior

Should be able to install without any issues

Current Behavior

Apparently xhal-base package is not created at all but listed as a dependency. libxhal-base.so is indeed created, but packages as xhal. Another (potentially bigger issue) is while xdaq is tied to a particular version of xerces-c and includes it, it is omitted in provides list:

it is not listed as installed, so in case one has the repos above enabled, another copy of xerces-c will be installed during installation of xhal. After some investigation found an interesting case of ...hmm... rebranding?

build xhal rpms
copy them to the repository
run yum install xhal\*

At a minimum, something like this should be all that's required (I think it was also mentioned in the original issue @mexanick reported and fixed), as the dependencies will be picked up by RPM during the creation itself (and here they'll get the actual soname versions that they're being built against, which the xdaq packages do declare as provides). The binary packages may not need any explicit things here (but at least the current ARM build fails with an empty list), and on the ARM since we disable the auto deps it's handy in the case that packages eventually are installed via a card-based package manager.
