This also tweaks cdefs to make __overloadable usable outside of FORTIFY. It had to be FORTIFY-only before we had unmarked overload support in clang+Bionic. Bug: https://github.com/android-ndk/ndk/issues/402 Test: Internal master builds + `mma`. `mma` in Bionic fails if the change to ioctl is undone. Change-Id: Ib386b1786e1dca625e6d5a18682005adc734d9c1
