Embedding the symbol table can shift sections and flip relaxation

size differs from the previous pass.
This takes the same remedy as commit 35de7285d508 ("Arm: do a 4th
linking pass if necessary"), though the underlying cause differs:
here no symbol (dis)appears from the ELF symbol table; instead the
set of end markers emitted by tools/symbols legitimately changes,
because want_symbol_end() depends on code layout, and layout differs
between passes due to linker relaxation.

And I think there's no dependency on earlier patches, so this could go
in pretty much right away?
There is no any dependency and could go earlier then other patches.
Thanks.
