binutils 2.42.50.20240618-1FTBFS of mir 2.17, undefined references to stdlib with LTO

[Michał Sawicz]

With deps at 2024.06.18 things work:

```
$ git clone https://github.com/canonical/mir.git --depth 1
$ cd mir
$ apt build-dep . --snapshot 20240618T000000Z
$ dpkg-buildpackage -uc -us
```

Upgrading binutils causes a FTBFS
```
$ apt install binutils
# /var/log/apt/history.log
Commandline: apt install binutils
Upgrade: libctf-nobfd0:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), libbinutils:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), binutils-x86-64-linux-gnu:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), libctf0:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), binutils-common:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), libsframe1:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), libgprofng0:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1), binutils:amd64 (2.42-4ubuntu2, 2.42.50.20240618-1ubuntu1)

$ dpkg-buildpackage -uc -us

[Michał Sawicz (saviq)]

2.42.50.20240625 has the same problem.

[Matthias Klose (doko)]

in https://sourceware.org/bugzilla/show_bug.cgi?id=31982, people are not able to reproduce this with GCC 14, however when I'm trying, I get:

/usr/bin/ld: CMakeFiles/mir_unit_tests.dir/frontend_wayland/test_desktop_file_manager.cpp.o: in function `DesktopFileManager_can_resolve_from_valid_flatpak_info_Test::TestBody()':

is this something to fix in mir?

please could you also address LP: #2073451 in mir?

[Michał Sawicz (saviq)]

@doko this is just a warning, the actual error, further up, is this:
