Getting "clang70: error: unknown argument: '-mandroid'" error when I try to compile on macOS

[davidfekke]

I am getting "clang70: error: unknown argument: '-mandroid'" error when I try to compile on macOS. I think this may be because by default the mac uses a 'g++' alias to clang instead of the regular GCC compiler.

Here is the full error;

The library could not be configured for supporting multi-threaded
applications as the compiler options required on this system are not known.
See file INSTALL for details if you need multi-threading.

The options 'shared', 'pic' and 'dynamic-engine' aren't supported on this
platform, so we will pretend you gave the option 'no-pic', which also disables
'shared' and 'dynamic-engine'.  If you know how to implement shared libraries
or position independent code, please let us know (but please first make sure
you have tried with a current version of OpenSSL).

AFAIK, you can't build the openssl 1.1.0h with clang. Please specify the ANDROID_NDK_ROOT so that the script will create standalone toolchain and use the toolchain's gcc to compile.
