Comment (by kencu):

 it checks here (configure.ac)
 {{{
 dnl Do we need leading underscores on our symbols?

 AC_CHECK_PROGS(NM, nm)

 AC_MSG_CHECKING(for underscore before symbols)
 AC_CACHE_VAL(sasl_cv_uscore,[
     echo "int main(){int i=1; return 0;}
     void foo(){int i=6;}" > conftest.c
     ${CC} -o a.out conftest.c > /dev/null
     if (${NM} a.out | grep _foo) > /dev/null; then
       sasl_cv_uscore=yes
     else
       sasl_cv_uscore=no
     fi])
 AC_MSG_RESULT($sasl_cv_uscore)
 rm -f conftest.c a.out
 }}}

 and on my Mojave system, finds this:
 {{{
 configure:15311: checking for underscore before symbols
 configure:15327: result: yes
 }}}
