Hello,

just like the bsd-uthread patch, this patch changes every instance of
builtin_type_void_data_ptr in solib-related code to use target_gdbarch
associated builtin types instead.

Bye,
Ulrich

ChangeLog:

	* solib-svr4.c (LM_ADDR_FROM_LINK_MAP): Use builtin types of
	target_gdbarch instead of builtin_type_void_data_ptr.
	(LM_DYNAMIC_FROM_LINK_MAP, LM_NEXT, LM_NAME,
	IGNORE_FIRST_LINK_MAP_ENTRY, scan_dyntag, elf_locate_base,
	solib_svr4_r_map, solib_svr4_r_brk, solib_svr4_r_ldsomap,
	open_symbol_file_object): Likewise.
	* nto-tdep.c (LM_ADDR): Likewise.
