proposed fix

This is a stack overflow, and it has nothing to do with how WebKit invokes PCRE
- it's also reproducible with pcretest, versions 6.1 (used in WebKit) and 6.6
(latest).

PCRE has a mode for systems with limited stack, where it no longer uses
recursion (at the cost of some performance, reportedly). There are also some
limits that can make deep recursion fail with an error, but I don't see how we
could use them, as long as we want to work with Yahoo widgets.

This patch just defines NO_RECURSE. There is no noticeable delay when opening
the test.
