The kernel abi for this was merged in v5.8, just as the qemu 5.1
merge window was closing, so this slipped to the next dev cycle.
Changes from v11:
* Fix the reported bti-2 crash.
Work around a bug in ld from binutils 2.34 (in our docker image,
and Linaro's aarch64 ubuntu 20 host), which has been fixed in
binutils 2.35 (in my laptop's cross-compiler installation).
Changes from v10:
* Include Phil's plug of interp_name memory leak.
* Convert error reporting to Error api.
* Mirror the kernel's code structure for parsing notes
(though Error means that it's not exactly the same).
* Split aarch64 stuff from basic note parsing patch.
Changes from v9:
* Split what is now patch 7 into 3 more (pmm).
* All prerequisites are now upstream.
