Optional steps #1

If you happens to own multi core server (which I do), you can utilize that to make command.

make -j4

Where 4 is your core number, parameter is-j{core_number}.

Optional steps #2

Upon restarting apache, I get such error.

Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP

Luckily, the solution is quite easy.

sudo a2dismod mpm_event && sudo a2enmod mpm_prefork
sudo /etc/init.d/apache2 restart
