[PATCH 0/4] target/s390x: CC fixes

[Ilya Leoshkevich]

Hi,

This series fixes two issues with updating CC. David was suggesting a
bigger rewrite [1], but I did not dare do this (yet). Instead, these
are targeted fixes: patch 1 helps with installing Fedora, and patch 3
addresses something I noticed when reviewing the code. Patches 2 and 4
are tests.

Best regards,
Ilya
