-It is expected that QEMU will advance its minimum supported version of
-rustc to 1.77.0 as soon as possible; as of January 2025, blockers
-for that right now are Debian bookworm and 32-bit MIPS processors.
-This unfortunately means that references to statics in constants will

 QEMU also supports version 0.60.x of bindgen, which is missing option
 ``--generate-cstr``.  This option requires version 0.66.x and will
 be adopted as soon as supporting these older versions is not necessary
