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. On request by Sam Ravnborg <sam@ravnborg.org>, I've added it to asm-generic/vmlinux.lds.s. I've also moved there the stabs debug section, used the new macro in i386 linker script and added DWARF debug section to that. In the truth, I've not been able to verify the difference in GDB behaviour after this change (I've seen large improvements with another patch). This may depend on my binutils version, older one may have worse defaults. However, this section is present in normal linker script, so add it at least for the sake of cleanness.
