[PATCH 5.7.2] OPTIMIZE= during perl make

This makes a -g-rebuild of perl as easy as

  rm *.obj
  make OPTIMIZE="-g -Dregister=" perl

No need to edit cflags any more.

I also included a new target test_harness to run the harness, and
moved dependencies on $(PERL)$(EXE_EXT) from _test_prep to the caller
of _test_prep.

The latter change avoids a lengthy no-result delay during _test_prep.
My current OS/2 setup builds 6 flavors of Perl executable, and does
tests with all of them, so this delay (and the resulting "screen
corruption") gets in the way.

Enjoy,
Ilya
