Avoid UUOC in install_deps.sh
The file ##build_files/build_environment/install_deps.sh## contains the following line:
THREADS=`cat /proc/cpuinfo | grep processor | wc -l`
The command within the backticks is a [[ http://catb.org/jargon/html/U/UUOC.html | Useless Use Of Cat ]].
A more compact way of writing the same thing (saving two subprocesses) is
THREADS=`grep -c processor /proc/cpuinfo`
or (using POSIX-preferred command-substitution parentheses instead of backticks)
THREADS=$(grep -c processor /proc/cpuinfo)
But the most compact, and least Linux-specific, way is to use the ##nproc##(1) command from the [[ http://www.gnu.org/software/coreutils/manual/html_node/nproc-invocation.html | GNU coreutils package ]]:
THREADS=$(nproc)
