There's a merged pull request on the void-packages repository

xen: update to 4.14.1.
https://github.com/void-linux/void-packages/pull/27751

Description:
Also:
* Split qemu data files into a xen-qemu-data package.  All of the
qemu-xen firmware belongs in /usr/share, not /usr/libexec, because it
is qemu data and not a host executable.
* Bring back a musl patch for hvmloader.  This came from Alpine Linux,
though we had it in the tree a long time ago.  Update stdint_local.h
with the version from Alpine.
