That sounds like something produced during the build. Normally you
wouldn't version control such a thing. You version control the stuff
produced by humans, not the stuff that can be easily reproduced by the
machine. (You might make an exception to this rule if the build process
is very slow, or if you want a snapshot of the build output, but
normally it's a good rule.)
If some parts of this file need versioning and other parts change with
each build, then the usual trick is to put the versioned parts in a
different file, and copy from that file during the make. The versioned
file will change rarely, the non-versioned file will change with every
build.

I think that sounds like the usual solution.
