[xml] [PATCH] variables need 'extern' in static lib on Cygwin

[Michael Haubenwallner <michael haubenwallner ssi-schaefer com>]

While the dllimport/dllexport macros now work for Cygwin, using the
static library still requires variables to be declared as 'extern'.
This is a regression of c65c9e8ee07e2dab0647392c2bd1795a5bc99829,
found+fixed by Bruno Haible using static libxml embedded in gettext.
