[coreboot] build failure: cannot move location counter backwards

[Darren Hart]

I'm new to coreboot and just trying to get it to boot into qemu. I've
tried using SeaBios as well as just copying "yes" to payload.elf. I
updated the Makefile to use gcc 4.5 instead of the 4.4 that ships with
my distribution (Ubuntu 10.10):

dvhart@doubt:~/source/coreboot.svn
$ gcc --version

-HOSTCC = gcc

 HOSTCFLAGS := -I$(srck) -I$(objk) -g
 HOSTCXXFLAGS := -I$(srck) -I$(objk)

I followed the instructions here:
http://www.coreboot.org/Build_HOWTO
to configure for qemux86 with a 256K ROM.

The build output and resulting failure follow. Am I doing something dumb
or have I hit a legitimate bug?
