[PATCH v2 3/4] build: Add libgrust as compilation modules

[Arthur Cohen <arthur.cohen@embecosm.com>]

From: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>

Define the libgrust directory as a host compilation module as well as
for targets.

ChangeLog:

	* Makefile.def: Add libgrust as host & target module.
	* configure.ac: Add libgrust to host tools list.

gcc/rust/ChangeLog:

	* config-lang.in: Add libgrust as a target module for the rust
	language.
