rust-1.2.0: fix llvm link issue cause "multiple crates" error

Fixes #6 (until something else comes along and adds another '-L') At the same time remove the no longer needed patch to tweak llvm version checking, we disable those checks in configure now.

+Subject: [PATCH 10/10] mk: tell rustc that we're only looking for native libs
+ in the LLVM_LIBDIR
+
+This fixes the case where we try to re-build & re-install rust to the
+same prefix (without uninstalling) while using an llvm-root that is the
+same as the prefix.
+
+Without this, builds like that fail with:
+	'error: multiple dylib candidates for `std` found'
+
+See https://github.com/jmesmon/meta-rust/issues/6 for some details.
+
+May also be related to #20342.
