The syscall name was changed explicitly so compilation broke instead of allowing programs using the raw syscall to use the time64 struct timespec with a syscall expecting the old one. Since we have modern glibc and musl, we can just force clock_gettime usage. The previous patch also broke y2038 support. Not revbumping, since c085deae94a6fbd3d113eaceaaee4f0f947e091d didn't either.
