What is the goal of daily update of BFD_VERSION_DATE?

Could you give me more background of it.

e.g.:

I think you'd be better off asking on the binutils list.

My guess is that it's so that snapshots can be exactly identified.
FWIW I'm not really convinced it is all that useful.

Yes.  HJ distributes his "Linux binutils", based on snapshots of
mainline plus some extra patches.  Other people distribute snapshots
too.  The date gives us some chance of tying Joe User's bug report to
the source.

I agree that it doesn't make much sense for gdb..

I'm curious how much use you really get out of it for binutils.
Alternatively, Would it be sufficient if "src-release" instead stuck the
git commit hash into some file?
It's not of major importance to me, more like a rainy day thing.  But if
it's high value to you then I wouldn't change a thing.
