tristate.conf was dropped because it is not needed to build a
modules.builtin (although dropping it introduces a few false positives
into modules.builtin support), and doing so avoids one round of
recursion through the build tree to build it.  But kallmodsyms support
requires building a mapping from object file name to built-in module
name for all builtin modules: this seems to me impossible to accomplish
without parsing all makefiles under the influence of tristate.conf,
since the makefiles are the only place this mapping is recorded.

So bring it back for this purpose.  (Thanks to the refactoring in
the 5.16 timeframe, this is basically a reimplementation of commit
8b41fc4454e36fbfdbb23f940d023d4dece2de29 rather than a simple
reversion.)

I don't see the need, see the review of next patch.
