Joshua Root  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.

Ned Deily  added the comment:

Thanks for the PR! This seems like a borderline feature rather than a bug so, 
unless there is a compelling reason to backport it to 3.8.x, I'm just going to 
push it to master for release in 3.9.0 (as of alpha 6).

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

[Joshua Root]

New submission from Joshua Root :

The path associated with the -isysroot compiler flag can be supplied either as 
a separate argument or in the same argument as -isysroot itself. The places in 
library code that do special handling of this flag should support both forms, 
but currently only support the two separate arguments form. This means that the 
flag may not be removed when pointing to a nonexistent SDK or when a different 
SDK is specified in the user's CFLAGS, and at worst a ValueError is raised in 
compiler_fixup.
