Seems to be successfully compiling loads of stuff now...
Add XPLATFORM_ANDROID to configure, used it for OpenSSL compile.test.
Add ANDROID_GLES2_LFLAGS (-Wl,–allow-shlib-undefined) and pass it through to (all!) OpenGLES2 compile-tests.
Accept -Wl* as input to compile.test and pass it on in LFLAGS.
Back to android-9, of course, 10 doesn't exist from an NDK perspective and 11 isn't out yet.
