An upstream change broke our build scripts in a very confusing way. I think KBUILD_EXTRA_SYMBOLS was added in 2.6.26. Since we no longer need to build on anything older than 2.6.32 I can use that instead of copying the Module.symvers from the other build directory and relying on the build scripts passing -I Module.symver to modpost. I just need to find a suitable system to check it on. All made more difficult by working from home....
