This is PR28414.
Previously LLD was unable to link following:
(failed with undefined symbol bar)
```
Version script:
SOME_VERSION { global: *; };
.global _start
.global bar
.symver _start, bar@@SOME_VERSION
_start:
jmp bar
```
Manual has next description:
//
.symver name, name2@@nodename
In this case, the symbol name must exist and be defined within the file being assembled. It is similar to name2@nodename.
**The difference is name2@@nodename will also be used to resolve references to name2 by the linker**
https://sourceware.org/binutils/docs/as/Symver.html
//
Patch implements that. If we have name@@ver symbol and name is undefined,
name@@ver is used to resolve references to name.
