This is a partial fork of the Android bionic C library, taken from:

https://android.googlesource.com/platform/bionic/+/5e62b34c0d6fa545b487b9b64fb4a04a0589bc13/libc

The purpose is to build into the Android Starboard port necesary parts of bionic that are not available on all versions of Android that we support, including:

• ifaddrs (and its dependencies) - Used by SbSocketGetInterfaceAddress, but not available until API 24.
