James Henderson 4ba1777a2d [ELF] Remove checking for spurious '@' at the end of dynamic sym names
llvm-readobj currently has a bug (see PR40097) where it prints '@' at
the end of unversioned dynamic symbols. This bug will be fixed in a
separate later commit, but these tests need fixing first.

George Rimar 3e8a461bdf [ELF] - Give a symbol version extracted from name a priority over version set by script.
This fixes PR33712.

Imagine following script and code:

VER1 { global: foo; local: *; };
VER2 { global: foo; };

.global bar
bar:
.symver bar, foo@VER1

.global zed
zed:
.symver zed, foo@@VER2

We add foo@@VER2 as foo to symbol table, because have to resolve references to
foo for default symbols.
Later we are trying to assign symbol versions from script. For that we are searching for 'foo'
again. Here it is placed under VER1 and VER2 at the same time, we find it twice and trying to
set version again both times, hence LLD shows a warning.
Though sample code is correct: we have 2 different versions of foo.

Patch gives a symbol version extracted from name a priority over version set by script.
