Subject: [PATCH] Bug 435441 - Handle weak symbols as global for redirection
Weak symbols are global but with lower precedence, so they should
be handled the same way as global symbols during malloc replacement.
This fixes valgrind on musl 1.2.2 when it is not patched with a
soname (as is done on Alpine Linux).
