I most recently tried building a34823df61df65168aa40ef5e82e44defd4a0138, but I've also tested the latest commit about a month ago, and I don't see any related commits to GCC 11 since then.
What's the problem? Describe what went wrong.
When attempting to build dolphin with GCC 11, I used Fedora 34, it seems to fail with this error:

What steps will reproduce the problem?
Try to build dolphin using gcc 11. I've also used binutils 2.35, and glibc 2.33 if this affects anything.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
I believe so, but I don't see any reason why the failure would have already been fixed. It looks like a conflict of constants in x86 jit, which appears to still exist.
Is the issue present in the latest stable version?
Yes
If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
Not a regression
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Please let me know if you need a full log, but the above should be enough to get the jist.
