crossgcc/buildgcc: Add comment about URLs and jenkins builder

Add a comment to try to lower possible confusion later if the jenkins
tool builder fails to build a new tool.  The URLs for the packages that
are downloaded are checked against known locations so that someone can't
maliciously download a package from somewhere and run it on the build
server.  This provides a little bit of security, but could confuse
someone if they don't realize it.
