For the record, I figured out why it "works now but didn't work before".
cat
#!/bin/sh
unset EMACSLOADPATH
exec -a "emacs" "/home/jonas/src/emacs/emacs/src/emacs" "$@"
*appears* to work as intended (by me), but in actuality it uses the
libraries from where the package is installed, *not* from the source
repository. I didn't inspect closely enough before to notice this.
Also, the name of the wrapper script does not actually matter. (Use
of --dump-file doesn't help.)
Of course that doesn't work if Emacs hasn't actually been installed.
For completeness sake I should mention that I have once more confirmed
that using a symlink works (the libraries from the repo are used), but
an alias does not work (the files from the installation are used).

No need to reopen, as far as I am concerned, but I thought it was
worth mentioning this here.
