Hmmm.... following up on your point I've noticed something strange. futimens is missing from the NDK (r9b; it's not in any headers and the libc.so files are the same all the way back to android-9), which is why I thought it's missing from Android generally. The NDK is by far the easiest way to cross-compile since it provides a standalone cross-compilation toolchain. It is however present in...

.../libc.so", I can see futimens() is present. On the others, it is definitely missing.
