automation: Disable QEMU build with Clang older than 10.0

[XEN PATCH] automation: Disable QEMU build with Clang older than 10.0

Posted by Anthony PERARD 10 months, 2 weeks ago

Since QEMU commit 74a1b256d775 ("configure: Bump minimum Clang version
to 10.0"), or QEMU v8.0, Clang 10.0 is now the minimum to build QEMU.

QEMU 8.0 fails to build on Ubuntu Bionic.

Notes:
    I've tested that change here, with QEMU v8.0.2:
