File php-4.3.1-dlopen.patch of Package php4

1. Don't open extension modules with RTLD_LAZY: better to fail obviously at
load-time rather than obscurely at run-time if they have undefined
symbols.

2. Do open extension modules with RTLD_DEEPBIND, to try and avoid symbol
conflicts between independent modules and their dependencies.
