As of nightly-2019-01-07, rustc fails on platforms with older libstdc++, i.e. CentOS 6.

Build LLVM with -static-libstdc++ on dist builds
444bc74 
This commit is intended on fixing a regression from rust-lang#57286 where the
distributed LLVM shared library unfortunately depends on a dynamic copy
of libstdc++, meaning we're no longer as binary compatible as we
thought! This tweaks the build of LLVM as out distribution is slightly
different now, and is hoped to fix the issue.

Closes rust-lang#57426
