on the basis that this is clearly necessary for the BTF stuff to pass
its tests at all, but with the understanding that I'll be bringing a
bunch of this stuff back, probably in a different not-run-by-default
'ctf' testsuite, along with an option used by that testsuite to turn
fallback to BTF off, so I can keep using these tests to test sanity of
the kernel's CTF generation :) (I do plan to introduce more CTF tests in
binutils, and am doing so, but the sheer diversity of the Linux kernel's
type system makes it a hard testcase to replace, and I can't require
*that* in foundational toolchain stuff like binutils!)
