[issue38360] single-argument form of -isysroot should be supported

Wed Apr 22 07:34:30 EDT 2020

Joshua Root <josh+python at root.id.au> added the comment:

That ValueError I mentioned causes build failures for extension modules whenever the CFLAGS in sysconfig contains an -isysroot flag in the single arg form. We ran into it a lot in MacPorts on Mojave and Catalina. So I would consider it a bug, and would prefer to backport to all branches that are open for bug fixes.
