Commit Message

FFI: Workaround for platform dlerror() returning NULL.

Contributed by mcclure.

(cherry picked from commit 478bcfe52)

The `ffi.load()` implementation assumes the string returned from
`dlerror()` is non-NULL and immediately dereferences it. This may lead
to a crash on some platforms like Android (Oculus Quest) where it is
possible.

This patch adds the corresponding check and the default "dlopen failed"
error message.
