Yes, that's correct. This code in configure is used for w32 and for w64:

# Use ASLR, no-SEH and DEP if available
if test "$mingw32" = "yes" ; then
    for flag in --dynamicbase --no-seh --nxcompat; do
        if $ld --help 2>/dev/null | grep ".$flag" >/dev/null 
2>/dev/null ; then
            LDFLAGS="-Wl,$flag $LDFLAGS"
        fi
    done
fi

See resulting file:

bin/debug/w64/config-host.mak:LDFLAGS=-Wl,--nxcompat -Wl,--no-seh 
-Wl,--dynamicbase -Wl,--warn-common -m64 -g
