[O] [bug] latex export of link in footnotes

[Christophe Rhodes]

Hi,

The below org file in 7.7 and today's git, when exported through LaTeX,
results in an invalid link in the footnote, pointing to an undefined
label named Foo.  The link in the body is correctly exported to the
automatically-generated sec-1 label; HTML output seems correct in both
cases.

* Foo
  Here is some text
* Bar
  Here is some more text[fn:1]; see section [[Foo]].

* Footnotes

[fn:1] see section [[Foo]].

Thanks,

Christophe
