I would say it was expected...

I think your build dir is corrupted by a previous build.

You should have old .o file without .d file, and thus the .o file is not
refreshed (check the date of cpu_loop.o). We cannot cleanup that before
starting the build. The purpose of the cleanup in configure was to avoid
this kind of problem but I did it badly.

If you want to check incremental build, cleanup your build dir, checkout
v4.20 or master, build it, and then build the PR branch. it will work:
it's tested.

If you build 4.2.0, then master and then PR, the build dir will be
corrupted by the build of master that removes the .d files without
removing the .o files. So when you build the PR, cpu_loop.o  file
remains and is not rebuild with the new values in cpu.h.

We can't do anything to avoid that now, except removing all .o files
under *-linux-user...

Sorry for the mess...

Thanks,
Laurent
