Tools backport request for Xen 4.14

[Julien Grall <julien@xxxxxxx>]

Hi Ian & Jan,

Would it be possible to consider backporting to 4.14 the following tools 
commit:
d25cc3ec93eb "libxl: workaround gcc 10.2 maybe-uninitialized warning"

This would help to build Xen tools on Debian Testing with GCC 10. I 
haven't build itself myself, so I can't promise this is only one :).
Cheers,
