Restore the gcc specific link generators.

* build/toolset.jam (inherit-generator): New parameter 'generators-to-ignore'.
* tools/gcc.jam: Ignore *link* generators when inheriting. Declare the
  gcc specific generator.
* test/gcc_runtime.py: Test that <link-runtime>static is correctly handled.
  The gcc specific generator is necessary exactly for that reason.
