suggestion: force removal and reinstallation of eaccelerator on php upgrade

[Olivier Mueller]

Reason: when you upgrade php, for example for 5.2.2 to 5.2.3, and forget
to uninstall and reinstall eaccelerator, it will break web services (if
php is active as module) and php -i will look like:

[om at calypso ~]$ php -i
[om at calypso ~]$

I presume it's possible to define such a behaviour ?  eAccelerator has
to be compiled on each php version change.
