Works perfectly fine on every version of GCC I've used, from 5 to 12, and I've
done this countless times in various configurations.
If there is any kind of problem here, GCC needs to fix its junk build process,
instead of being the one package on the planet requiring some absurd
out-of-directory build.

It's GNU software, so go figure.
A mysterious "No such file or directory" error here can also indicate the
binary isn't finding the libc loader for some reason, due to bad rpath or some
such. Use 'readelf -a' to ensure the C library loader path is correct.
