Xcode 11.2 has been failing for a while through the following error. This change ignores that failure until we can fix it properly...
```

There is a Darwin code path in the qb configure scripts and as far as I
can tell it has not been tested heavily in a long time.
This will expose this code path for travis builds with only clang which
will make it easier to test qb changes without breaking Darwin support.
I am surprised that this hasn't already happened...
Some things to note are.
* It appears gcc is really clang on macOS.
* Both C89_BUILD and CXX_BUILD were ommitted because they are broken in
ways I can not fix. In the event any interested parties wish to fix
these issues they can be easily added.
* This will use the default macOS version available with travis which is
currently 10.13. Other version(s) can be specified if desired, I am
not sure which versions are best to test. See the following link for
more details.

This is the correct change to prefer the builtin zlib.
Revert "(QB) Bake in zlib by default, make zlib as dynamic library dependency"
This reverts commit 2713e792ca.
Revert "(QB) Change behavior - if HAVE_ZLIB = no, that doesn't mean"
This reverts commit f66fe5e16b.
* qb: Fix OpenGLES build.
The gl core video driver requires at least OpenGLES 3 and
OpenGL 1 is not compatible with OpenGLES 2 or 3.
* travis: Test OpenGLES builds on linux.
