More support macOS

Now, on macOS, such command gets error:

https://github.com/rbenv/ruby-build and https://github.com/pyenv/pyenv/tree/master/plugins/python-build provides fallbacks to use homebrew bundled package or build method to use latest OpenSSL.

ruby-build/python-build's method:

1. Detect os type (https://github.com/rbenv/ruby-build/blob/master/bin/ruby-build#L103)
2. If is macOS, check whether use breaked OpenSSL (https://github.com/rbenv/ruby-build/blob/master/bin/ruby-build#L1015)
   • OpenSSL bundled macOS is always breaks because it is older libreSSL, so, ruby-build/python-build search Hombrew's OpenSSL.
3. If use breaked OpenSSL, build OpenSSL by sources (https://github.com/rbenv/ruby-build/blob/master/share/ruby-build/2.5.1#L1)

I want this support for PHP. This support helps also phpenv/phpenv#77 .

@madumlao 's approach is similar. However, I think this is too expensive. In my cases, php-build should use macOS bundled zlib/bzip2 as possible.

I would like you to discuss this points and provide more supports for macOS users.
And I report test results of https://github.com/madumlao/php-build/tree/osx-zlib on this issue.

Thanks for getting in touch. We're absolutely open to contributions. Please let me know how you get on. :)

Ah, I see this relates to php/php-src#3616. We probably want this patched at an earlier level than master. I guess they'll merge it where they want. Just, master branch is for PHP 7.4 I think.

[mizunashi-mana]

I implemented my idea on https://github.com/mizunashi-mana/php-build/tree/add-fallback-for-openssl. This provides only openssl fallback, so, we cannot build PHP with just this patch on Mojave.
However, macOS includes libxml2/zlib/bzip2/iconv/libedit/freetype now and when php/php-src#3616 will be merged, we will be able to use php-build with only openssl fallback.

And, found a bug for https://github.com/madumlao/php-build/tree/osx-zlib:

@madumlao We should specify the --with-openssl option but not --with-openssl-dir. You can see the test results at https://travis-ci.org/mizunashi-mana/php-build/jobs/446023483.

We probably want this patched at an earlier level than master.

@GrahamCampbell Yes, I think so. Actually, I'm waiting any reactions of PHP team and searching any better solutions.
Because we can use macOS_SDK_headers_for_macOS_10.14.pkg in the short term for Mojave, we still have time for discussions.
