permissions error building external payload

[David Griffith]

I ran into a problem with my project to get the coreboot build process to 
download, build, and include openbios.  Things go okay until this point:

Creating config files...ok.
/usr/bin/xsltproc
Building OpenBIOS for x86
Building...
error:
   GEN   target/include/openbios-version.h
   GEN   forth/version.fs
  HOSTCC host/kernel/dict.o
/home/dave/proj/coreboot/coreboot/payloads/external/OpenBIOS/openbios/kernel/dict.c:320:1: 
fatal error: opening dependency file /.d: Permission denied
  }
  ^
compilation terminated.

I can compile openbios just fine by going into 
payloads/external/OpenBIOS/openbios/ and typing "make".  What am I doing 
wrong?

Hi David,
  You need to add a rule to payloads/external/Makefile.inc as well.
Here's a start:

payloads/external/OpenBIOS/openbios/obj-x86/openbios-builtin.elf
openbios: $(top)/$(DOTCONFIG)
  $(MAKE) -C payloads/external/OpenBIOS all \
    CONFIG_OPENBIOS_MASTER=$(CONFIG_OPENBIOS_MASTER) \
    CONFIG_OPENBIOS_STABLE=$(CONFIG_OPENBIOS_STABLE) \
    CONFIG_OPENBIOS_REVISION=$(CONFIG_OPENBIOS_REVISION) \
    CONFIG_OPENBIOS_REVISION_ID=$(CONFIG_OPENBIOS_REVISION_ID)

You'll probably want to add some additional variables to configure
openbios to use the coreboot toolchain. All of the variables will need
to be exported or passed on the command line between
external/Makefile.inc and external/OpenBIOS/Makefile.

With your changes and the ones to Makefile.inc, I get to this point:
