[gentoo-dev] [PATCH] php-ext-source-r3.eclass: Rebuild exts should dev-lang/php[threads,debug] change.

[Jaco Kroon <jaco@uls.co.za>]

If these use flags change then the extension dir changes too, requiring
extensions to be rebuilt.

The downside of this change is that different versions of PHP can no
longer have different USE values for threads and debug.
