Bug#182654: missing ntp_adjtime on alpha

[Daniel Schepler]

This is causing build failures of ntp (see bug #184172).

According to the glibc ChangeLog's, ntp_adjtime was changed to an
alias of adjtimex.  It doesn't seem that change got propagated to the
alpha port, though.  It still appears in /usr/include/sys/timex.h,
though.
