solenv/gbuild/UnoApiTarget.mk at that location has

ifeq ($(origin gb_UnoApiHeadersTarget_select_variant),undefined)
$(eval $(call gb_Output_error,gb_UnoApiHeadersTarget_select_variant
must be defined by platform))
endif

I expect that gets set by...

gb_UnoApiHeadersTarget_select_variant = $(if $(filter
udkapi,$(1)),comprehensive,$(2))

in solenv/gbuild/platform/unxgcc.mk

and for that to be included by

solenv/gbuild/platform/linux.mk

and for this architecture that should (I think) be included by 

solenv/gbuild/platform/LINUX_GODSON64_GCC.mk

so to debug why that might not be happening I'd look into config.log
and search for the line that starts with
CPUNAME=
and see what that is to check that first
