I wasn't keeping track.  It should be left as it is then.

Nope, it's not; it's for functions gcc generates calls to.  Miscellaneous
code goes in misc; the only directories one could say are for "internal"
code are csu and elf.

It certainly should not be used by anything that doesn't need it for a good
reason.  But such changes can be evaluated on their individual merits when
they come up; it seems reasonable to move the list to Makeconfig
(especially since it's affected by config.make information).
