shrink expanded binary tarballs during installation

[Giuseppe Maxia]

(from question #106904)
I propose you to use the code below to shrink the size of the archive as we certainly won't use test and debug files with MySQL SandBox :

clean_dirs.sh :

DIR=$1
if [ ! -d "$DIR" ]
then
  echo "Directory not found or not provided $1"
  exit
fi

cd $1
rm -rf docs/ mysql-test sql-bench/ bin/*test* bin/*debug*
strip bin/* lib/* 2>/dev/null
cd ..
echo "Directory $1 cleaned"

maybe an option should be added to make_sandbox and other utilities
