Yeah, that's there, a symlink to ~source/include/asm-i386

Well, from the obj directory there's include/asm/arch/ldt.h (704 bytes).

Should I delete all of them, then?

Let's see...

find . -size 0b | xargs rm

Oh that's a _much_ happier build.  It's got various warnings about iplicit 
declarations and unused variables but none of those big long chains of "in 
file included from" and the build made it all the way to the link stage 
before dying: 

  CC      lib/semaphore-sleepers.o
  CC      lib/sha1.o
  CC      lib/string.o
  CC      lib/vsprintf.o
  AR      lib/lib.a
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/um/sys-i386/built-in.o(.text+0x3b60): In function `load_TLS':
: undefined reference to `indirect_set_thread_area'
collect2: ld returned 1 exit status
  KSYM    .tmp_kallsyms1.S
nm: '.tmp_vmlinux1': No such file
No valid symbol.
make[2]: *** [.tmp_kallsyms1.S] Error 1
make[1]: *** [_all] Error 2
make: *** [all] Error 2

This is progress!

What would you like next from me?
