Android is a Java based OS, which happens to use Linux as kernel, Google can very easily change it to something else.
Only these set of C and C++ libraries are available to native applications on Android, which happen to be compiled to a .so anyway, to be loaded inside ART/Dalvik.
Trying to link into any other GNU/Linux library that happens to be on the devices, but isn't part of that list, will trigger an app termination, starting with Android 7.

Also, many POSIX APIs have been removed from the kernel and require extra wrapper libraries, if they can be emulated at all.
