Description of problem:
It seems like the conditionals for %{?_enable_debug_packages} and %{with benchtests} have been mixed up in the spec file. Building with "--define '_enable_debug_packages 0' --without benchtests" leads to build failures.

Version-Release number of selected component (if applicable):
glibc-2.28-127.el8

How reproducible:
Everytime with "--define '_enable_debug_packages 0' --without benchtests" options at build-time.
