nginx module compilation fails on macOS w/ Xcode 10.2.

Issue report

Are you sure this is a bug in Passenger? Yes.

Question 1: What is the problem?

What is the expected behavior?

The nginx Passenger module should compile successfully with the latest version of Xcode installed (v10.2.1).
What is the actual behavior?

Compilation succeeds with Xcode <v10.2, but >=v10.2 fails with the following incantation:
```
CPATH=/usr/local/opt/openssl/include:/usr/local/opt/pcre/include LIBRARY_PATH=/usr/local/opt/openssl/lib:/usr/local/opt/pcre/lib passenger-install-nginx-module --auto --prefix=/tmp --nginx-source-dir=/tmp/nginx-1.16.0 --languages=ruby,python,nodejs --extra-configure-flags="--sbin-path=/usr/local/sbin/nginx --conf-path=/usr/local/etc/nginx/nginx.conf --error-log-path=/var/log/nginx.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --user=root --group=wheel --with-threads --http-log-path=/var/log/nginx.log --with-pcre --with-pcre-jit --user=root --group=wheel --with-http_ssl_module --with-http_v2_module"
```
...yielding the following logs:

Log output.
``` Welcome to the Phusion Passenger Nginx module installer, v6.0.2. This installer will guide you through the entire installation process. It shouldn't take more than 5 minutes in total. Here's what you can expect from the installation process: 1. This installer will compile and install Nginx with Passenger support. 2. You'll learn how to configure Passenger in Nginx. 3. You'll learn how to deploy a Ruby on Rails application. Don't worry if anything goes wrong. This installer will advise you on how to solve any problems.

Found: yes -------------------------------------------- Automatically download and install Nginx? Nginx doesn't support loadable modules such as some other web servers do, so in order to install Nginx with Passenger support, it must be recompiled. Do you want this installer to download, compile and install Nginx for you? 1. Yes: download, compile and install Nginx for me. (recommended) The easiest way to get started. A stock Nginx 1.15.8 with Passenger support, but with no other additional third party modules, will be installed for you to a directory of your choice. 2. No: I want to customize my Nginx installation. (for advanced users) Choose this if you want to compile Nginx with more third party modules besides Passenger, or if you need to pass additional options to Nginx's 'configure' script. This installer will 1) ask you for the location of the Nginx source code, 2) run the 'configure' script according to your instructions, and 3) run 'make install'. Whichever you choose, if you already have an existing Nginx configuration file, then it will be preserved. => Proceeding with choice 2. -------------------------------------------- Where is your Nginx source code located? => /tmp/nginx-1.16.0 -------------------------------------------- Where do you want to install Nginx to? => /tmp -------------------------------------------- Extra Nginx configure options If you want to pass extra arguments to the Nginx 'configure' script, then please specify them. If not, then specify nothing and press Enter.

How can we reproduce it? Please try to provide a sample application (or Virtual Machine) demonstrating the issue. Otherwise, if we can't reproduce it, we might have to ask you a number of followup questions or run certain commands to try and figure out the problem.

With Xcode >=v10.2 installed and xcode-selected, run passenger-install-nginx-module.

Question 2: Passenger version and integration mode: OSS v6.0.2.

Question 3: OS or Linux distro, platform (including version): macOS v10.14.4 (18E226)

Question 4: Passenger installation method: RubyGems, no Gemfile

Question 5: Your app's programming language (including any version managers) and framework (including versions): Ruby 2.6.0, installed through RVM 1.29.7.

Question 6: Are you using a PaaS and/or containerization? If so which one? Nope.

Question 7: Anything else about your setup that we should know? Thanks for looking into it! :sparkles:
