We try to use ethereum contract in webassembly but it was failing due to
some symbols missing. To fix this I disabled compilation of some modules
for js tag.

accounts/abi/bind/auth.go does not compile because it depends on accounts/external, which depends on signer/core, which does not compile under WebAssembly. We will fix it by removing the dependency on signer/core.

The dependency is now removed.

This should no longer be needed, after the change in #23275

Unfortunately this change wasn't enough, here is what I get:

        imports github.com/ethereum/go-ethereum/accounts/abi/bind
        imports github.com/ethereum/go-ethereum/accounts/external
        imports github.com/ethereum/go-ethereum/signer/core/apitypes
        imports github.com/ethereum/go-ethereum/internal/ethapi
        imports github.com/ethereum/go-ethereum/consensus
        imports github.com/ethereum/go-ethereum/core/state
        imports github.com/VictoriaMetrics/fastcache
        imports golang.org/x/sys/unix: build constraints exclude all Go files in /home/maxmati/go/pkg/mod/golang.org/x/sys@v0.0.0-20210510120138-977fb7262007/unix

I don't know go-ethereum at all so it's hard to fix for me.

We have merged another update to remove more dependencies of accounts/abi/bind, it should compile now.
