Sam Clegg 6c393e9d74 [lld][WebAssembly] Fix for weak references to data symbols in archives 
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
