Dynamic linking experiments are stumbled by unconditional "--export-table"

[pepyakin]

I've discovered flags like --pic/--shared in the latest LLD (seems to be not yet available in the LLD shipped with rust). But when I try to use them I'm getting this LLD error:

lld: error: -shared/-pie is incompatible with --export-table

I tried to pass --import-table to override the rustc passed --export-table, however, LLD doesn't support that, and fails with

lld: error: --import-table and --export-table may not be used together

Do you have any idea how to proceed here?

There's a bit of discussion on the original PR, and it seems like if LLD doesn't support both flags then we should remove the argument from rustc and require users to pass in an explicit value.

Oh, the problem might be deeper, since overriding of stack size doesn't seem to work either.

I believe the stack size aspect was addressed by rust-lang/rust#57337

Should have been fixed in rust-lang/rust#57861, so closing.
