runtime: Go 1.22.0 fails to build from source on armv7 Alpine Linux [1.22 backport]

[gopherbot]

@cherrymui requested issue #65601 to be considered for backport to the next 1.22 minor release.

@gopherbot please backport this to Go 1.22 release. This is a regression, causing runtime crashes with GOARM=7.

Change https://go.dev/cl/567555 mentions this issue: [release-branch.go1.22] runtime/internal/atomic: correct GOARM=7 guard at a DMB instruction

Closed by merging 8fe2ad6 to release-branch.go1.22.
