And the -L options apparently point to a library that contains mempcpy,
which means an Android API >= 23, although said Termux header defines
__ANDROID_API__ to a value < 23 ? That's an inconsistent setup that would
cause us an inordinate amount of effort to support.

Thanks. I dug around but neither searching online or in the Termux packaging code reveals how Termux's version of the NDK selects the API level of the libc. (Unless the situation is that there's only one? In which case the solution would be to set `__ANDROID_API__` to match it, as per this issue: https://github.com/termux/termux-packages/issues/2469 )

If you have any knowledge about this it would be good to know!

For the moment my workaround is to configure projects with `CPPFLAGS=-D__ANDROID_API__=<MAX-API-SUPPORTED-BY-DEVICE>`.
