Need backport for use after free regression in binutils 2.34

[Tatsuyuki Ishi]

There has been a regression in binutils 2.34 [1] and this results in buggy build artifacts for software like DXVK. Although the fix is included in 2.35, it's still a good idea to backport this to 2.34.

A backport commit has already been published [2], and I had success applying the patch to the Ubuntu package source with minor modifications (aligning paths, also CHANGELOG had a conflict but I just removed it because it doesn't affect functionality). The resulting build produces correct output for DXVK, thus confirming the fix.

Unfortunately, because of the way binutils-mingw-w64 is built, this is liable to be complex to fix.

In Focal, I could upload a new version with the patch, but I’m not sure how to go about getting an update into “proposed”.

In Groovy, binutils-source is 2.35, so the only possible fix is to build with that, which would mean getting the Debian 8.11 package synced.

Status changed to 'Confirmed' because the bug affects multiple users.
