dev-lang/rust: reimport rust-1.34.2 from github.com/smaeul/portage-overlay/
it's old, but uses the now stable llvm-8 and is suitable for building esr more important: it doesn't suffer from a bug where cflags are bleeding into the compile env when adding cross compile crates, this makes it a good base for exploring these unknown waters. if you're going to use with system-llvm, please check out the nifty patchset and drop those targeting llvm into /etc/portage/patches/ Signed-off-by: Steffen Kuhn <nielson2@yandex.com> Signed-off-by: Jory Pratt <anarchy@gentoo.org>

+Subject: [PATCH 04/14] Require static native libraries when linking static
+ executables
+
+On ELF targets like Linux, gcc/ld will create a dynamically-linked
+executable without warning, even when passed `-static`, when asked to
+link to a `.so`. Avoid this confusing and unintended behavior by always
+using the static version of libraries when trying to link static
+executables.

+Subject: [PATCH 08/14] Correct minimum system LLVM version in tests
+
+Since commit 9452a8dfa3ba, the new debug info format is only generated
+for LLVM 8 and newer versions. However, the tests still assume that LLVM
+7 will use the new debug info format. Fix the tests (and a comment in
+the code) to match the actual version check.
