OK. I applied everything on top of the branch you suggested, and now it's
compiling. But seemingly I don't have too much success; on a quick check
(perf record -p <pid> -g, perf report --inline) I don't get anything marked
as (inline), but I get these warnings:

BFD: Dwarf Error: found dwarf version '6931', this reader only handles version 2, 3 and 4 information.
BFD: Dwarf Error: found dwarf version '18896', this reader only handles version 2, 3 and 4 information.

and so on for many seemingly random version numbers.

It may have been that the stack traces I happened to check don't actually
have any inlined functions in them (the load was a bit different from what
I've looked at earlier), but the BFD errors are new from what I can see.
