[PATCH] xen/build: Use -Wflex-array-member-not-at-end when available

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This option is new in GCC-14, and maps to MISRA Rule 1.1.  The codebase is
clean to it, and Eclair is blocking.

I really ought to have posted this before we regressed the tree, but oh well.
Better late than never.
