[not ready] Upgrade to openssl-1.0.2

[ljbade]

This PR attempts to upgrade to OpenSSL 1.0.2, it should also allow x86-64 Android builds.

However for some reason none of the OpenSSL CFLAGS are found by configure.

I can't see any change between the mason openssl-1.0.1l and openssl1.0.2 that would cause this.

The mason libcurl built fine against openss-1.0.2

So I don't know why this doesn't work.

@kkaefer @springmeyer Either you have an idea as to what is causing the the CFLAGS to not come through?

Looks due to missing libssl.pc (https://travis-ci.org/mapbox/mapbox-gl-native/jobs/49416922#L695):

Package libssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libssl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libssl', required by 'OpenSSL', not found

#823 is the direction we're going in now, right? Can we close this PR out?
