Our Pythons currently patches distutils to install packages to
/usr/lib(64)/pythonX.Y/site-packages when the $RPM_BUILD_ROOT environment
variable is set (and to /usr/local/lib(64)/pythonX.Y/site-packages otherwise).
With the deprecation of distutils [1] we want to change the patch to create
and use a different sysconfig install scheme [2].
However, we have realized that macros defined as %(%{__python3} ...) don't
"see" the environment variables set by rpmbuild because they are expanded earlier
and hence e.g. %{python3_sitelib} evaluates to
/usr/local/lib/python3.X/site-packages -- which is not desired.
To be able to reliably detect an RPM build environment by checking
the presence of the $RPM_BUILD_ROOT environment variable,
we manually set it in the macro definitions.
Since %{buildroot} in not fully populated
(e.g. it can expand literally to
/home/anna/rpmbuild/BUILDROOT/%{NAME}-%{VERSION}-%{RELEASE}.x86_64),
we don't use it here.
The variable simply needs to present in the environment.
See also the analysis of the build failures when this is not done [3].
