The following commit

  5da6aea375cd ("objtool: Fix find_{symbol,func}_containing()")

fixed the issue where overlapping symbols weren't getting sorted
properly in the symbol tree.  Therefore the workaround to skip adding
empty symbols from the following commit

  a2e38dffcd93 ("objtool: Don't add empty symbols to the rbtree")

is no longer needed.
