First, this inference of mine wasn't right because
`semantic-symref-filepattern-alist' has the following entry:
    (cperl-mode "*.pl" "*.PL")

I had the same idea, but most practical solution would be to add an
entry like this to `semantic-symref-filepattern-alist' in
feature/fix-mode-names-overlap branch:
    (LaTeX-mode "*.ltx" "*.sty" "*.cls" "*.clo" "*.bbl")
