[lld][WebAssembly] Fix for weak references to data symbols in archives

Authored by sbc100 on Oct 16 2019, 4:07 PM.



Fix a bug where were not handling relocations against weakly undefined
data symbol. Add a test for this case. Also ensure that the weak
references to data symbols are not pulled in from archive files by
default (but are if -u <name> is added to the command line).

Fixes: PR43696
