[wwwdocs] [RFA] Update gcc-4.7/changes.html to document -mcpu=cortex-a7

[Matthew Gretton-Dann]

All,

The attached patch updates gcc-4.7/changes.html to document the addition 
of support in the ARM backend for Cortex-A7 via the -mcpu=cortex-a7 
command line option.

The wording is based upon that used for Cortex-M4 in gcc-4.6/changes.html.

Can someone please review, and if appropriate apply the patch?

Thanks,

Matt
