Now at last there is some kind of "progress". Last thing I tried was
replacing my current .config with that of my previous kernel (3.2.1-r2)
and at least the make ran all the way up to the point where it should
link everything to build vmlinux, only now it tells me it couldn't
find vmlinux.o.

The last couple of lines from the make output:

Essentially the same error as previously with mounts.o, and after
every LD comes an ls -Al ... line like above, which I never saw
before in my make outputs. Don't know where that comes from.

I'm now back where the troubles began, the vmlinux.o error was
the first I encountered after my last successful build.
Maybe a careful search of a diff of the .config files will
give me some idea.

By now you're probably somewhat tired of devoting your time
to this problem, so thank you for all your efforts to help me.
If I ever solve this, you'll hear from me (which doesn't mean
the thread is closed. If someone is still curious... ;-) )

Kind regards, Michael
