WinCE Perl EVC4 support

WinCE Perl EVC4 support

- CCTYPE has always been empty string in Makefile.ce, makedef.pl does not
  complain about this, but it is a bug, so fix it

- create a profile for a EVC4 arm build

- put -GS- and -GL flags into compiler version specific defs so VC6 era
  EVC4 will work

- don't delete ..\lib\Config.pm, it was made by win32/Makefile, for a
  Desktop Perl, deleting this breaks miniperl when it loads its pure perl
  modules for cross MakeMaker module building, and requires rebuilding the
  Desktop Perl so miniperl works again. CE Perl has its Config.pm in the
  xlib\$(MACHINE) dir
