[PATCH] Fix PCRE detection on OSX.

You're misreading the patch - it just skips the check to see if PCRE
is available without any additional -L / -I options, it will still do
all the checks to see if PCRE is available in /usr/local, /opt/local
and all other common prefixes...

In short, it compiles nginx with PCRE on OSX, without requiring user
to do the "configure" work by hand.

Best regards,
