           Product: Wine
           Version: 10.7
          Hardware: aarch64
                OS: Linux

When compiling wine for aarch64, a build regression appeared in Wine 10.7 when
using clang (any version).

Error is that register x18 is used, and clang reports it as an hard error.

[00:04:11] fatal error: error in backend: Invalid register name "x18".
