emxbind doesn't read library name from .def file

[Yuri Dario]

The module name used by emxbind when building dynamic libraries is not read from .def file: it is built from output name, but this prevents dotted names for the dll.

This change to emxbind.c allows using LIBRARY name from def file:

case _MD_LIBRARY:

/* Create a DLL. Save the initialization and termination

policies after choosing default values for unspecified values. */

if (stmt->library.name[0] != 0)

module_name = xstrdup (stmt->library.name);
