[libava/win32]: Don't add dll[im/ex]port attributes to libgcj, unless dll build

[Mohan Embar]

Hi People,

>>> I actually prefer the .def file option discussed here:
>>> http://gcc.gnu.org/ml/java/2003-08/msg00076.html

To my naive eyes, requiring a separate .DEF file for such matters
would create a dual-maintenance issue. I realize that the number
of exported functions is relatively static, but I don't see harm in such
macros, even if a different macro is needed for CNI-related exports
vs. JNI-related exports.

The only other disadvantage I can see is that they would be confusing
for non-Windows folks.

I'd appreciate any education / enligtenment on this issue.
