Ok, the comments under:
\libiberty\make-relative-prefix.c line 217 clearly said it should work.
(it also give us an example about path handling)

/* Given three strings PROGNAME, BIN_PREFIX, PREFIX, return a string
that gets
   to PREFIX starting with the directory portion of PROGNAME and a relative
   pathname of the difference between BIN_PREFIX and PREFIX.

   For example, if BIN_PREFIX is /alpha/beta/gamma/gcc/delta, PREFIX is
   /alpha/beta/gamma/omega/, and PROGNAME is /red/green/blue/gcc, then this
   function will return /red/green/blue/../../omega/.

   If no relative prefix can be found, return NULL.  */

static char *
make_relative_prefix_1 (const char *progname, const char *bin_prefix,
			const char *prefix, const int resolve_links)

PS: make_relative_prefix() internally call make_relative_prefix_1().
