+Subject: [PATCH] [DynamicLibrary] Fix build on musl libc
+
+Summary:
+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, giving errors like:
+
+```
+error: cannot initialize return object of type 'void *' with an rvalue of type 'FILE *const *' (aka '_IO_FILE *const *')
+    EXPLICIT_SYMBOL(stderr);
+    ^~~~~~~~~~~~~~~~~~~~~~~
+```
+
+Add an explicit cast to fix that problem.
