[Xen-devel] asm/asm-offsets.h: No such file or directory

Hi!

I found another problem building
<URL:http://xenbits.xensource.com/linux-2.6-xen.hg>:

#v-

I was building with a separate output files's directory (putting
O=... on make's command line).

asm-offsets.h gets created in O/include/asm-i386, but no O/include/asm
symlink is created (which should point to asm-i386).  After creating
that symlink the build was able to continue.

Being mostly ignorant of Linux's build system, I don't know the proper
way to tell the build system to create that link.

 Thomas
