Probably because distfiles from opensource.apple.com, which used to be manually generated and uploaded, now redirect to github automatically-generated tarballs.

Portfile patch which includes new checksum hashes and directory name fix

[edolnx (Carl Perry)]

I found that the new files have a different prefix because of an error in their generation on GitHub. The extracted directory has an extra gcc- prefix, which I'm accounting for in the post-extract section. This is now building with the bootstrap variant on my G5 Mac running 10.4.11. The diff of my Portsfile to the one in the current repository is attached.

I found that I needed to do a similar thing to ld64 in #68538 and instead of renaming the directory, I made a symbolic link. I'm unsure which approach is preferred.
