[5/8] solib handler rework: solib-target

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

Hello,

this converts the solib-target handler, used by arm-wince and
i386-cygwin targets, to the cross-platform form.

Bye,
Ulrich


ChangeLog:

	* arm-wince-tdep.c: Include "solib.h" and "solib-target.h".
	(arm_wince_init_abi): Call set_solib_ops.
	* i386-cygwin-tdep.c: Include "solib.h" and "solib-target.h".
	(i386_cygwin_init_abi): Call set_solib_ops.
	* solib-target.c: Include "solib-target.h".
	(solib_target_so_ops): Make global.
	(_initialize_solib_target): Do not set current_target_so_ops.
	* solib-target.h: New file.
	* Makefile.in: Update dependencies.
