That's kind of the point @mrserb is making.  Your binaries may need this license, but you have made a change which affects **everyone** building OpenJDK.

These are changes to the devkit build, which is something that has to be manually invoked separately from the OpenJDK build.  The change you've made here will bundle the GCC license in every build. 

This file was included on a build I just did on GNU/Linux with clang:

I haven't checked Windows & Mac but I presume this would also get bundled there too, where, again, gcc is not even being used.  I don't see anything in this PR that would prevent that from happening.

I don't see an explanation in this PR or the bug as to **why** this license is now needed.  `gcc` has been used to build for a long time, but this is not updating an existing license, but adding it.  So I presume something from `gcc` is now being bundled which requires this.  If so, inclusion of this license should be tied to whatever that option is.
