I had a look, and the way makeinfo generates HTML is, hmm, creative.

For an internal reference (@xref) like this it creates a new file based 
on the reference name -- Extended-asm-with-goto.html -- and that file then 
only contains a single line which is a redirect back to the original page.  

And here is our inconsistency since it encodes blank characters as %20

  <meta http-equiv="refresh" content="0; 
  url=Extended-Asm.html#Extended%20asm%20with%20goto">

whereas in the document itself it reads

  <a name="Extended-asm-with-goto">

As far as I can tell both approaches to encode blanks would be fine.

The problem is that they should be used consistently, which is not
what happens on gcc.gnu.org running makeinfo 4.13.

That'd be my assumption.  Which version are you using locally that
does not exhibit this behavior?

My guess is you are using a more recent version of makeinfo.  Updating 
gcc.gnu.org will be hard (since its a standard RHEL 6 system) and I
won't have the time to hack around this (applying sed magic, say).
