I got curious and looked into git history to find why that was done
in the first place.

'git blame configure.tgt' points at a4ce5b0d0204 as the commit that
converted the old .mt files into configure.tgt.

And then:

 $ git blame a4ce5b0d0204^ -- ./config/sparc/linux64.mt

points at:

            * config/sparc/linux.mt (TDEPFILES): Add sol2-tdep.o.
            * config/sparc/linux64.mt (TDEPFILES): Likewise.

Which is... drumroll... a big nothingburger:

So, nothing to see here, move along.  :-)
