Figuring out how to build hbm-minigbm with NDK

Hi, I'm trying to build hbm-minigbm static library with Android NDK so I can create a repo containing the prebuilts. Currently I'm stuck at

error[E0425]: cannot find function `makedev` in module `sys::stat`
   --> hbm/src/utils.rs:16:16

error: could not compile `hbm` (lib) due to 1 previous error

Does this mean the project will have to create it's own implementation of makedev for Android targets ?
