Hello,

On certain machines we have, GDB fails to build because the libexpat
version it has installed is so old that the XMLCALL macro is not
defined (we have version 1.95.8). The attached patch should fix
the problem.

        * gdb_expat.h (XMLCALL): Define if not already defined.

Tested on 2 different x86-linux machines: One that does have a recent
libexpat, and another that has an older one.

OK to apply?

Thanks,
