I think whats going wrong in the presubmit test failure is that you did not provide a definition of libc.include.sys_ioctl and we don't have an existing one, yet you are adding a dependency on it.

I'll bet you need a `add_gen_header` in libc/include/CMakeLists.txt for this.  Checkout how it's done for sys/select.h.def as an example.
