How to build PHP 5.4 without mysqlnd?

[Reko Turja]

Greetings!

Compiling mysqlnd into PHP is excess baggage for us not using MySQL in any 
shape or form. Yet it seems that there is no way for disabling in in the 
php5 building process. Setting WITHOUT_MYSQL=yes in make.conf does not do 
anything, removing --enable_mysqlnd in Makefile results in staging errors 
etc.

So, any pointers how to make the build complete without mysqlnd, preferably 
so that I didn't need to manually fix the port files after every update?
