php: add opcache option

Browse source 
Add a Zend OPcache option and tweak the build system into being
cross-compile friendly.
The OPcache extension allows for a neat intermediate bytecode cache in
memory to avoid reinterpreting/recompiling php scripts on multiple runs.
Make it an option since this takes up valuable RAM.
