I've written the following code which seems to achieve this but I'm
wondering if theres already a macro that accomplishes much of this?

  # does condor_compile suffer from condorbug 19343
  AC_MSG_CHECKING([if condor_compile suffers from bug 19343])
  condor_compile_output=`$CONDOR_COMPILE $CC -print-prog-name=ld`
  condor_compile_retcode=$?
  if [[ "$condor_compile_retcode" = 1 ]]; then
    AC_MSG_RESULT([yes])
    LD=/usr/bin/ld
  else
    AC_MSG_RESULT([no])
  fi

Cheers
