Note: Separate patch for another function: find_and_open_solib as
requested.

Attaching a patch and Chengelog entry for the function
nto_find_and_open_solib preceding nto_init_solib_absolute_prefix. There
I did not see any use of the make_cleanup/do_cleanups functions
(assuming open and openp always return). Therefore xfree is used
directly. (Maybe line break of the first xsnprintf statement is not
correctly placed, what does GCS say here?)

	* nto-dep.c (nto_find_and_open_solib): Use xstrprintf followed by
	a cleanup instead of alloca to be consistent with function
	(nto_init_solib_absolute_prefix).
