File ovmf.e063f8b8a53861043b9872cc35b08a3dc03b0942.patch of Package xen

From: Gerd Hoffmann <kraxel@redhat.com>
Date: Mon, 20 Jan 2025 09:40:31 +0100
Subject: e063f8b8a53861043b9872cc35b08a3dc03b0942

BaseTools/Pccts: set C standard

The prehistoric code base doesn't build with ISO C23.  Set the C
standard to C11 (for both clang and gcc) so it continues to build with
gcc 15 (which uses C23 by default).
