[PATCH] gccrs: add selftest-rust-gdb and selftest-rust-valgrind "make" targets

[David Malcolm <dmalcolm@redhat.com>]

Add "make" targets to make it easy to run the rust selftests under gdb
and under valgrind via:
  make selftest-rust-gdb
and
  make selftest-rust-valgrind
respectively, similar to analogous "make" targets in the C and C++
frontends.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.

OK for trunk?

gcc/rust/ChangeLog:
	* Make-lang.in (selftest-rust-gdb): New.
	(selftest-rust-valgrind): New.
