I forgot to mention payloads/external/Makefile.inc.  Here is the entry I 
made:

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

With your example, I doubt it would get to the point where I got stuck 
because you don't have the x86 cross-compiler installed.

Hi David,
  I think clearing MFLAGS & MAKEFLAGS should fix the issue for you:

$(MAKE) -C payloads/external/OpenBIOS all \
                HOSTCC="$(HOSTCC)" \
                CONFIG_OPENBIOS_DEVEL=$(CONFIG_OPENBIOS_MASTER) \
                CONFIG_OPENBIOS_STABLE=$(CONFIG_OPENBIOS_STABLE) \
                CONFIG_OPENBIOS_REVISION=$(CONFIG_OPENBIOS_REVISION) \
                CONFIG_OPENBIOS_REVISION_ID=$(CONFIG_OPENBIOS_REVISION_ID) \
                MFLAGS= MAKEFLAGS=
