Other time functions (e.g. settimeofday) set errno to ENOSYS if IMPL_NEWLIB_TIME_FUNCS is not set. adjtime should probably do the same.
errno should be set to EINVAL in this case according to adjtime's man page.

In contrast to other time function implementations (e.g.
settimeofday) and its man page,adjtimedoes not seterrnoin case it fails.There are two possible scenarios for
adjtimeto fail at the moment:errnoshould be set toEINVALaccording to the man pagesettimeofday) returnENOSYSin this caseThis pull request fixes both.
Maybe this is something that should also be fixed in some of the older stable releases which are still in maintenance period. What do you think? I would love to see it fixed for v4.4 at least, which is the version I discovered this on 馃槈
