[Aboriginal] addition - log file of build

[scsijon]

I was wondering if when ./build.sh was run, a second copy of the 
displayed build process was logged into a text file, maybe with the 
filename in the format build-$date-$time.log, so it can be investigated 
if problems are found then or later, or you want to check something that 
occurred during the build happened in the right way.
