gcc 4.8.2 online docs broken

[Ryan Mansfield]

A number of the links in 4.8.2 docs are broken (trunk seem to be OK).
http://gcc.gnu.org/onlinedocs/4.8.2/gcc/ has 404s for the following:

http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options
http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/IA-64-Options.html#IA-64-Options
http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/PDP-11-Options.html#PDP-11-Options
http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/TILE-Gx-Options.html#TILE-Gx-Options
http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/Conditionally-supported-behavior.html#Conditionally-supported-behavior

The w3c validator page says there's 54 broken links. It looks like 
anything with a "-" in the URL is affected.
