Contemporary versions of Fedora automatically set SOURCE_DATE_EPOCH
based on the changelog entry date stamp. In scenarios where it already
is defined, we do not want to redefine it.
Additionally, when building the libvirt package in an Open Build Service
instance, the spec file is not present in %_specdir, but instead in %_sourcedir.

IIUC this macro can be specified on the rpmbuild's cmd line. Can't it set the %_specdir to be the same as %_sourcedir? Michal

I'm inclined to just delete all the source epoch stuff from the spec and rely on the build environment set it if they want reproducable builds.

This is not exposed as a macro despite attempts to do so[1].

We can just wrap the current setting in "%if 0%{?rhel}" then, so we
honour the setting from Fedora.

That doesn't really change the need for this. I'm building this in an
OBS system, and I want that property to take effect properly.
