Clear static_links in reread_symbols
-fsanitize=address pointed out a use-after free in
objfile_register_static_link. The bug turned out to be that
reread_symbols does not clear the static_links field; this leaves a
hash table that is filled with freed pointers.
Jan's (now quite old) idea of replacing reread_symbols with a simple
delete/new still seems good to me, and it's worth noting that it would
have avoided this bug.
Tested by the buildbot and by observing the change with
-fsanitize=address.
