Quick and dirty, using the macros of showkeys:

\documentclass{article}
\usepackage{showkeys}
\usepackage{hyperref}

\makeatletter
\@ifpackageloaded{showkeys}{%
  \@ifundefined{SK@@label}{}{%
    \let\SK at hypertarget\hypertarget
    \def\hypertarget#1{%
      \SK@\SK@@label{#1}%
      \SK at hypertarget{#1}%
    }%
    \ifx\SK at ref\@empty
    \else
      \AtBeginDocument{%
        \SK at def\hyperlink#1#2{\SK@\SK@@ref{#1}\SK at hyperlink{#1}{#2}}%
      }%
    \fi
  }%
}
\makeatother

\begin{document}
Target: \hypertarget{abc}{TARGET}
\par
Link: \hyperlink{abc}{LINK}.
\end{document}
