Workaround for three known issues in OpenSSL for Android.

[xsacha]

1. The OpenSSL Configure script runs a s/^-no-/no- script that ruins our CFLAGS input when input from ./config.
   On this line: https://github.com/openssl/openssl/blob/OpenSSL_1_1_0-stable/Configure#L560
   Tracked here: Unsupported option: -no-canonical-prefixes on Android openssl/openssl#3493

2. The android-* targets use -mandroid that doesn't work on clang.
   To be fixed in future versions with this pull: Build for Android with Clang openssl/openssl#2229

3. ./config can only set up x86 and armv7 targets. It ignores armv8, mips32, mips64 and x86_64.
   Tracked here: [rt.openssl.org #4536] Android arm-v8/arm64/aarch64 Support openssl/openssl#2490

As a solution, use our CFLAGS on top of a generic linux target and use the main Configure script.

As far as I know, Configure should be used when you are bringing your own CFLAGS and config should be used to automatically set up sane flags.
For Android, the latter is not working very well.

With this change, Android now compiles for all versions of OpenSSL on GCC and Clang.

I don't understand how this links related to the fact that now we are using ./Configure instead of ./config...

[xsacha]

It is because ./config propogates this bug.
If you change this to ./config you will experience the current failure in Travis with -no-canonical-prefixes or any other -no-* CFLAG

[xsacha]

I just changed ./Configure back to ./config without changing anything else I get:
***** Unsupported options: no-canonical-prefixes

Using ./Configure, I see -no-canonical-prefixes correctly placed in the arguments to gcc/clang.

There is no other way this script can be written. I am not sure what you are wanting here.

Note: Also dropped outdated check for architecture. Since CMake 3.7+ is requirement of building Android now, the check is redundant

This one kept in case if somebody still maintaining Hunter fork with taka-no-me toolchain support and want to receive latest updates. Anyway it's not related to the current patch, please submit this separately.

I am not sure what you are wanting here

You're using the same code with the same links to documenation as in #807. #807 was closed, why do you expect me to merge this one?

As far as I know, Configure should be used when you are bringing your own CFLAGS and config should be used to automatically set up sane flags

Any link to documentation with this statement? This is main requirement for me. All your arguments have "works for me" type, it's not appropriate.

There are two generations of build system. First is the build system used in OpenSSL 1.0.2 and below. The instructions below apply to it. Second is the build system for OpenSSL 1.1.0 and above. Its currently available in Master through Git. The instructions are similar, but not the same.
OpenSSL is configured for a particular platform with protocol and behavior options using Configure and config.
https://wiki.openssl.org/index.php/Compilation_and_Installation#Configure_.26_Config
You use Configure and config to tune the compile and installation process through options and switches. The difference between is Configure properly handles the host-arch-compiler triplet, and config does not. config attempts to guess the triplet, so its a lot like autotool's config.guess.
Mac OS X can have issues (its often a neglected platform), and you will have to use Configure:

Okay, looks good.

Please update PACKAGE_INTERNAL_DEPS_ID of OpenSSL:

Although it actually doesn't affect any result, should be using the ANDROID_SSL_ARCH instead of CMAKE_ANDROID_ARCH to determine 32/64 since I work it out anyway.
Fixed.
