This patch from Ralf Grosse Boerger makes debugging more comfortable.

With this patch it's possible to 

- determine the according source code line for each asm statement
  (objdump -dS)
- determine the source code file for each asm statement 
  (objdump -ddl)

This isn't exactly trivial because cache_as_ram_auto.c gets compiled to
assembly and converted by a perl script afterwards.

This patch solves the problem 
- by extending cache_as_ram_auto.inc with debug information and line
  numbers
- by correcting the perl calls (".text" --> "\.text")
- by creating a disassembly with source code and line numbers.
  (ctr0.disasm and
  coreboot.disasm)

There's one minor downside to the patch: A complete abuild run takes up
around 1.6G instead of about 700MB now. But I'm sure this is quite
reasonable for the benefits.
