Comment (by MichalMMac):

 I am **not** able to reproduce necessity of SYSTEM_VERSION_COMPAT=1 on my
 primary machine (11.12.1 with both Xcode a CLI tools installed. Tools path
 pointing to /Applications/Xcode.app/Contents/Developer )

 However on macOS 11.1 with only CLI tools installed unless I use
 SYSTEM_VERSION_COMPAT=1 build fails. Build logs in attachments. I am going
 to upgrade this system to 11.2.1 and see if it changes anything.
