perl: fix build failure in GCC10

[dwmw2]

The perl Configure file was matching GCC 10 against "1*" and treating it
as GCC 1, causing ABI breakage and segfaults.

Cherry-pick the upstream patch which fixes it to check against (e.g)
"1.*" instead, which will make it work for hundreds more GCC versions
to come.

This supersedes #12178 in which we're being cruel to a potential contributor by asking them to "fix" their commit message without telling them how. If they knew what we were asking for, they might have done it in the first place.

@xinxijishuwyq here's what I think you were being asked for:
• Make it clearer that the patch is cherry-picked from upstream, and provide the reference
• Use the precise patch that was merged upstream (there are a couple of minor differences)
• Include an explanation of the problem in the OpenWRT commit message.

Thanks for your contribution to OpenWRT!

Wow. You mean telling them like I did here?

Please fix the initial comment.

@xinxijishuwyq Waiting on this. You can click on "..." on the top right side of the comment box and select "edit" to make changes.

That was 4 days ago and from what I can tell, you've done nothing with that information.

Further, packages has a template that the initial comment gets pre-populated with. It's there for a reason. Use it appropriately.
