This way we can compile multiple dictionaries at a time without
stepping on 'temp' file from different compilation steps:

    $ make -j8 -B
    ...
    make[1]: *** [Makefile:3082: espeak-ng-data/an_dict] Segmentation fault (core dumped)
    make[1]: *** Deleting file 'espeak-ng-data/an_dict'

Noticed build failure on NixOS when built package with 'make -j16':

    build flags: -j16 -l16 SHELL=bash

    touch dictsource/yue_extra
    cd dictsource && ESPEAK_DATA_PATH=/build/espeak-ng LD_LIBRARY_PATH=../src: ../src/espeak-ng --compile=yue && cd ..
    bash: line 1: ../src/espeak-ng: No such file or directory
    make[1]: *** [Makefile:3546: espeak-ng-data/yue_dict] Error 127
    make[1]: Leaving directory '/build/espeak-ng'
    make: *** [Makefile:831: all] Error 2

The fix is to add dependency on 'espeak-ng' similar to other rules.
