Some sub make modules point out directory to root e.g. /out-devicename-buildvariant

[ZeD73]

To fix this issue project build path must be
sb.append("OUT_DIR?=$(ANDROID_BUILD_TOP)/out-$(TARGET_PRODUCT)-$(TARGET_BUILD_VARIANT)\n")

That is module issue, not plugin issue.
If you want set OUT_DIR manually, please set OUT_DIR in buildspec.mk and do not include buildspec.mk.AndroidBuilder
