Most people get their GCC binaries for free, and no such source is going 
to be able to help for safety compliance or any other kind of 
certification.  Certification always costs time, effort and money.  But 
there are suppliers who provide toolchain binaries with commercial 
support contract, and which could help with certification.  I know Code 
Sourcery certainly used to be able to provide language compliance 
certification - I have no idea if they still can (it seems they are part 
of Siemens these days).  Maybe Red Hat (part of IBM) can do so too, and 
possibly others.  But perhaps that will give the OP a starting point.
