When using `-r' to produce relocatable code, you cannot just discard
all local symbols. The linker needs it again to fix up `base relative'
references in the GOT when producing the final shared library or even
a further `-r' pass. This is why the `-x' switch does not throw such
Renaming the symbol is not strictly necessary but it doesn't hurt either
and it's helpful for debugging, occasionally.
In any case, this is a deficiency in the binutils linker.
