[PATCH] D39297: [DynamicLibrary] Fix build on musl libc

[Keno Fischer via Phabricator via llvm-commits]

loladiro created this revision.

On musl libc, stdin/out/err are defined as `FILE* const` globals, and their address is not implicitly convertible to void *
(or at least gcc 6 doesn't allow it). Add an explicit cast to fix that problem.
