From 8e160daedd1a8c928024db648c2f851cddbbd000 Mon Sep 17 00:00:00 2001

Subject: [PATCH 14/16] Link stage 2 tools dynamically to libstd
Replaces an older patch by Samuel Holland. The RUSTC_NO_PREFER_DYNAMIC
env var was removed and replaced with the following logic in builder.rs.

The idea for this patch is to link stage2 tools dynamically as these will
be distributed (if built). Intermediate tools from previous stages will
be statically linked for convenience.

Rust 1.38 can't bootstrap itself. It has some ridiculous warnings enabled
by default which break this (even though the compiler obviously needs to
be able to compile itself just fine, that's what stage1 is all about).

Subject: [PATCH] Configure LLVM module PIC level
As of LLVM 9, this is required for 32-bit PowerPC to properly generate
PLT references. Previously, only BigPIC was supported; now LLVM supports
both BigPIC and SmallPIC, and there is no default value provided.
