+Subject: [PATCH] Use the identified python when building
+ System.Private.CoreLib (#19043)
+
+build.sh and build.cmd contain logic to identify a working version of
+python to use. System.Private.CoreLib ignores that and directly invokes
+'python', which may not work, or even execute a different program.
