This is needed so people can do things like:
%if %{with python3}
%global __python %__python3
%else
%global __python %__python2
%else
And than just use %__python, %py_build, %py_install,
%python_sitelib, ...
This is to ensure the right linker flags get propagated into binaries
accompanying python packages whenever distutils (or similar, env.
variables provided build flags aware) module is delegated to build them
(e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1541106). Instead of
using "%{__global_ldflags}" as the seed for the respective env. variable
one-off application, which would be a direct parallel to "%{optflags}"
seeding CFLAGS, use rather "${RPM_LD_FLAGS}" and "${RPM_OPT_FLAGS}",
as these are not directly bound to macros out of rpm proper (like
it would have been, e.g., on redhat-rpm-config package otherwise).
