[uml-devel] [patch 1/3] uml: add dwarf sections to static link script

[blaisorblade]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Inside the linker script, insert the code for DWARF debug info sections. This
may help GDB'ing a Uml binary. Actually, it seems that ld is able to guess
what I added correctly, but normal linker scripts include this section so it
should be correct anyway adding it.

Can we please have this added to include/asm-generic/vmlinux.lds.h so we
can share the definition.

Hmm, I'm going to leave for now, so I won't be able to handle this soon. If 
you can do that it'd be nice. Thanks and sorry for this request.
