-Subject: [PATCH] native libc detection: respect spaces in CC env var
-
-Zig has detection for when it is accidentally being called recursively
-when trying to find the native libc installation. However it was not
-working, resulting in a cryptic failure, because zig tried to execute
-a command which had spaces in it rather than tokenizing it.
-
-This improves the user experience of `zig cc` for systems that Zig
-does not support cross-compiling for.
-
-Closes #8960
