[O] Conditional link export?

[Oleh Krehel]

Hi all,

I'm writing a manual in Org-mode, with the intent to export both to
Texinfo and HTML. And I'd like to use this link for Texinfo:

    info:emacs#Packages

and this link for HTML:

    https://www.gnu.org/software/emacs/manual/html_node/emacs/Packages.html

They both link to the same information, but in different browsers
basically. How could this be done? I'm thinking of something like:

#ifdef TEXINFO
[[info:emacs#Packages]]
#else
[[https://www.gnu.org/software/emacs/manual/html_node/emacs/Packages.html]]
#endif
