build.sh and xen?

How to build kernel modules for xen?

Xen kernel is built with DEBUG and DIAGNOSTIC and the kernel modules are 
not so they conflict.

So I want to build modules with those options. But I don't see any 
build.sh config for building just modules. It was suggested that I build 
my modules for xen and not i386 because of different headers.

So I am attempting to build all with:

   time ./build.sh -U -m xen -a i386 build 

But then fails with:

dependall ===> lib/csu/i386_elf
#    create  i386_elf/crt0.d

What is supposed to populate that?

Any ideas?

Thanks in advance,
