arc: Fix potential invalid pointer access when fixing got symbols.

When statically linking, it can arrive to an undefined weak symbol of
which its value cannot be determined. However, we are having pieces of
code which doesn't take this situation into account, leading to access
a structure which may not be initialized. Fix this situation and add a
test.
