+ Added HB_CFLAGS_DYN variable to pass lib specific options
specially directed to compilation phase when building
to create a .dll. Currently this affects pcre and zlib since
these are included in harbour .dll.
* external/libhpdf/Makefile
* external/pcre/Makefile
* external/png/Makefile
* external/zlib/Makefile
+ Configured HB_CFLAGS_DYN for these libs to properly create
exported symbols in harbour .dll. This was a problem so far
for any non-mingw made harbour .dll.
