There would be an "Argument list too long" error when the build directory is longer than 200, this is caused by: headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u` The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle it, use the $(sort list) of GNU make which can handle the too long list would fix the problem, the header would be short enough after sorted. The "tr ' ' '\012'" was used for translating the space to "\n", the $(sort list) doesn't need this.
