do_compile failed with:
AttributeError: 'NoneType' object has no attribute 'lower'
A non-empty setup_requires makes setuptools run fetch_build_eggs(),
which enumerates every distribution in the native sysroot and calls
packaging.utils.canonicalize_name(dist.name). Under the setuptools/
Python 3.14 in the sysroot one distribution exposes a None name, so
canonicalize_name() crashes on None.lower() and aborts the build.
Extend the existing patch to drop the whole setup_requires block
instead of only setuptools_git. sphinx is only used by the build_sphinx
command (not run during do_compile) and is already provided via
DEPENDS, so removing it is safe and keeps setuptools out of the
fetch_build_eggs() path.
