Catch 2.9.2 enforces requirement libandroid

[fredcadete]

Describe the bug
Due to #1710, catch2 now requires linking to libandroid.

Expected behavior
Expected to have the same linkage requirements as before (STL only).
Or, expected a compile-time option to not have this requirement.

Reproduction steps

• Build 2.9.1 for Android, without linking to libandroid - OK
• Build 2.9.2 for Android, without linking to libandroid - linkage fails. Cannot find __android_log_print , from writeToDebugConsole

Platform information:

• OS: Ubuntu 18.04
• Compiler+version: Clang 8.0.0
• Catch version: 2.9.2

Additional context
In some cases it is desirable build for an Android target without expecting a requirement on the Android FW - libandroid included.

It's a nice feature btw, just would be good to opt out in some cases.
If this level of granularity in the compile-time options is not desirable by the project, I could live with patching my checkout of catch or undef'ing ANDROID at the inclusion point.

This should be doable in master now, can you test it out?

👌

With master, defining "CATCH_CONFIG_NO_ANDROID_LOGWRITE" avoids the link to libandroid.
