4Subject: [PATCH] _distutils/sysconfig.py: make it possible to substite the
5 prefix to target sysroot
6
7This is done by probing STAGING_INCDIR/STAGING_LIBDIRenv vars:
8not the most elegant solution, but distutils/sysconfig has been
9tweaked to do this for many, many year, and so it's easiest
10to replicate here as well, the original is
11meta/recipes-devtools/python/python3/12-distutils-prefix-is-inside-staging-area.patch
12
13I'm not sure exactly why setuptools now needs a copy, and what
14would happen to this module in light of distutils deprecation.
