Is the spec file using %configure?  That adds a lot of flags to the
configure script.  Similarly make _vs_ make %{_smp_flags}.

Have you tried 'printenv' at the top of the %check section?

Are you specifically running rpmbuild as the same user?  Or are we
talking about rpmbuild in some other environment (mock or Koji)?
There is a Koji bug which affects ksh %check in particular
(RHBZ#639275).
