Created attachment 595240 [details, diff]
Just idea for fix (not tested)

Internal portage “install-xattr” implementation (aka PORTAGE_INSTALL_XATTR_IMPLEMENTATION=”python”) require “-Z” flag to have option(s), but “install” (which “install-xattr” tries to mimic) from package “sys-apps/coreutils” documentation clearly states that flag do not have any options.

Consequences: on selinux sistems which use “python” “install-xattr” implementation by default all builds containing calls to “install-xattr” with “-Z” flag will fail at installation phase.

CommitDate: 2019-11-08 15:59:47 +0000 ignore -Z / --context
    The --context option accepts an optional argument, but only if it is
    passed via --context=arg. The argparse module does not deal with this
    To work around this, have argparse ignore this option, and filter out
    any remaining arguments that start with a hyphen and do not occur after
    a "--" delimiter.
