Exim upstream has dropped these intentionally in 4.90:
JH/22 Retire historical build files to an "unsupported" subdir.  These are
      defined as "ones for which we have no current evidence of testing".

If you want to revive exim4 on Hurd please test and open a upstream report
about this with your findings.

TIA, cu Andreas
