Maybe it will be automatically fixed as doko told me that he backported the fix in binutils.
The original form of this bug (i.e. "failed to find link section" when using GNU strip) should be fixed in binutils 2.31.1-11.
To get back to that being our only problem, we need to revert at least the attempt to use LLVM strip (i.e. https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/commit/d441237cacb871abfebec1353b4b64398a362b0b).
Whether to also revert -fno-addrsig (which should no longer be needed with the new binutils) depends on how we value "still has -dbgsym with older binutils (e.g. if backported for mesa)" compared to "potential few% space saving when linked with ICF".
(There's also #914021, where llvm*-dbgsym do exist but don't actually work; I don't know whether that will affect 7 after these changes)
