It's not something a compiler supports.  It just has to invoke the linker.

It's a trivial change to the linker options the compiler runs.
It's mandatory for a compiler package in F8.

Nonsense.  fpc should pass --build-id to ld by default just like gcc does.
Of course we didn't change every C program's build command for this either.

You misunderstand the feature.  If you produce ELF binaries, it applies to
you no different than anything else.  If you didn't produce ELF binaries,
you wouldn't have gotten the build error, so we know you do.  It applies.
