+Description: output to standard output while building.
+ The upstream build system puts all output in a log file rather than to standard
+ output. This can cause build timeouts on slow architectures and if the build
+ truely hangs makes it difficult to determine where it hung. Modify the build
+ system to output to standard output as it goes along.
