Broken link in gcc-4.8/changes.html

[Paolo Carlini]

Hi,

I just noticed a broken link (in case the issue is trivial I may get 
around to fixing it myself, but at the moment I don't know):

http://gcc.gnu.org/onlinedocs/gcc/X86-Built-in-Functions.html#X86-Built-in-Functions

(it appers twice)

Cheers,
Paolo.
