Dpgraph-io/badder v3.2103.0 depends on [github.com/dgraph-io/ristretto](http://github.com/dgraph-io/ristretto) v0.0.4-0.20210309073149-3836124cdc5a

the +s390x pragma is missing in the ./pkg/mod/github.com/dgraph-io/ristretto@v0.0.4-0.20210309073149-3836124cdc5a/z/simd/search.go imported file.

It should be  
// +build 386 s390x arm armbe arm64 mips mipsle mips64p32 mips64p32le ppc ppc64 ppc64le sparc

and not only  
// +build 386 arm armbe arm64 mips mipsle mips64p32 mips64p32le ppc ppc64 ppc64le sparc

Could it be corrected ? Thank you much. The pb applies to all ristretto 0.0.4 flavor.
