Subject: bug#28264: Accessing source directory through symlink produces false warnings

Package: emacs
Version: 26.0.50

Current master (cd0360f) on rhel7.

Emacs sources are in (eg) /tmp/emacs/git/master
cd ~
ln -s /tmp/emacs/git/master
~/master/src/emacs -Q

This results in the following new, spurious warnings:
    
    Warning: arch-dependent data dir '/:/tmp/emacs/git/master/lib-src/':
       No such file or directory
    Warning: Lisp directory '/:/tmp/emacs/git/master/lisp':
       No such file or directory
    
I would suspect recent changes to file name / symlink handling.
