I looked at the output.  If I read it correctly, the situation is like this:

The only build failure attributable to the “union wait” removal is tcsh.
 It just needs fixing.

For readdir_r, we were opting for a staged removal (flag it as
deprecated, then remove it after it is gone from POSIX).  But the
deprecation warning itself causes build failures.  This is the majority
of the failed builds Andreas' build service lists.

To me, this suggests to proceed with the “union wait” removal.
