PLF_CPP20_SUPPORT shouldn't be defined on Android NDK r24

[mikezackles]

As best I can tell, this detection is broken for the Android NDK, which ships with a copy of libc++ that does not implement the concepts header. Maybe it would be appropriate to use _LIBCPP_VERSION? There doesn't appear to be a way for users to override this behavior without patching.

For what it's worth, the relevant NDK issue is android/ndk#1530. They are shipping a libc++ that's something like 2 years out of date compared to the version of clang they're shipping.

Hey Zachary, thanks for getting back to me on this, I'm currently busy on the hive (C++ standards version of colony) implementation, but once done there (probably a month to go) will do this. Cheers! Matt

No problem -- no rush from me. Love the lib. Thanks!
