Oops, it appears that patch had some issues. Here is one I've tested
on i686-pc-linux-gnu, and does not break the shared object linking.

shared objects have their own global definitions of things like _etext,
which get pulled into the linker's symbol table.  I suspect that is wrong,
but I don't know how to fix it. Presumably _etext should either not be in
the shared object's symbol table at all, or simply not exported from it.

ok?
