Regression 19701 - LLD fails to link

[Andre Pany]

Hi,

could someone look at this regression, started with ~ 2.084
https://issues.dlang.org/show_bug.cgi?id=19701

LLD fails to link, in case you use dflags -Xfdocs.json
Kinke was kind and already analyzed the cause.

> _D4core8internal4hash__T6hashOfTaZQkFNaNbNiNexaZm without that 
> switch.
