AFAICT, the result in this case would be that the script comes to the
wrong conclusion about whether ucred.h is available. Wouldn't that
result in a build failure, or at least missing features? IOW, don't
we need to fix this test anyway?
However, if newer autoconf versions make only one test per header file
and not two, then +1 for updating. Should help a bit with configure's
speed problem.
