From what I can tell, mudflap has been around far longer than version 4.7 hasn't it?

Yes. I don't know exactly when it was introduced, but for instance in http://gcc.gnu.org/gcc-4.1/changes.html the following sentence shows that it already exists:

Some built-in functions have been fortified to protect them against various buffer overflow (and format string) vulnerabilities. Compared to the mudflap bounds checking feature, the safe builtins have far smaller overhead. This means that programs built using safe builtins should not experience any measurable slowdown.

Mudflap has been removed as of gcc 4.9, as it has been replaced by the sanitizers.
