Again, this is from the Android build, as the top level Android.mk calls:
include $(call all-makefiles-under,$(LOCAL_PATH))
Which includes all Android.mk files in all the sub directories
(regardless of any BOARD_GPU_DRIVERS value).
The error is that while we don't build the libdrm_intel module, the
android build system still throws a error when any
LOCAL_SHARED_LIBRARIES files aren't present in the larger build
environment.
Since the intel/Android.mk specifies
LOCAL_SHARED_LIBRARIES := \
libdrm \
libpciaccess
And in AOSP there is no libpciaccess module, it generates the error.
