The pytz package is a dependency of three others: babel, rpy2, and
tzlocal. And tzlocal is itself a dependency of rpy2. Babel is already
disabled with --disable-doc, and rpy2 and tzlocal are disabled with
--disable-r. It therefore makes sense to disable pytz when both
--disable-doc and --disable-r are given.

The pycparser package is a dependency of two others, cffi and rpy2,
which can be disabled with --disable-notebook and --disable-r
respectively. As a result we can disable pycparser when both flags are
present.

The pytz_deprecation_shim package is a dependency only of tzlocal,
which is already disabled with --disable-r.

Passing --disable-notebook to ./configure already disables the
argon2_cffi package, so it should be safe to disable its bindings
as well.

The soupsieve package is a dependency of beautifulsoup4, which is
already disabled with --disable-notebook. It should therefore be safe
to disable soupsieve under the same circumstances.

The sphinx_basic_ng package is solely a dependency of furo, which is
already disabled with --disable-doc. We should therefore disable
sphinx_basic_ng with --disable-doc as well.

The fastjsonschema package is solely a dependency of nbformat, which
is already disabled with --disable-notebook. We should therefore
disable fastjsonschema with --disable-notebook as well.
