Improve performances with CFLAGS

Improve compiled programs performances by adding CFLAGS at the end of your .bashrc. If you don't know what CFLAGS is, don't do it.

echo export CFLAGS="-O3 -pipe -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3 -fexpensive-optimizations -fprefetch-loop-arrays" >> ~/.bashrc
echo export ARM_ARCHITECTURE=True >> ~/.bashrc

SWAP for more "RAM" to avoid freeze on compilations

touch /swapfile
sudo chmod 600 /swapfile
sudo fallocate -l 4G /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon -s
