How do I in Lisp lookup the target of a symbolic link (if any)?

    file-symlink-p is a built-in function in `fileio.c'.

    (file-symlink-p FILENAME)

    Return non-nil if file FILENAME is the name of a symbolic link.
    The value is the link target, as a string.
    Otherwise it returns nil.

    This function returns t when given the name of a symlink that
    points to a nonexistent file.

    [back]

Arguably a bad name for the function, since *-p functions usually just
return t or nil.

I think you want file-truename or file-chase-links.
