Rationale: - There is no port under targets/ that would use it. All of them turn it off when building. - That's no surprise, as jerry-libc supports no barebone MCUs but posix targets with syscalls only. Actually, that's Linux only, because macOS builds have turned off the use of jerry-libc a while ago. - And there is no point in maintaining a highly restricted set of libc functions: as soon as someone wants to use JerryScript in a scenario that needs more functions than jerry-main, they have to choose a different libc (most problably the compiler's default one). I think that we should not keep supporting an otherwise unused library for the purposes of jerry-main on arm/x86/x64-linux only. JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
