cmd/compile: make.bash broken on dwarf (on linux-mips64le builder)

[ALTree]

The linux-mips64le-mengzhuo builder (and only that one) is currently broken, make.bash failing with:

# cmd/internal/obj
src/cmd/internal/obj/dwarf.go:57:18: cannot use dctxt (type dwCtxt) as type dwarf.Context in argument to dwarf.Uleb128put:
	dwCtxt does not implement dwarf.Context (wrong type for AddFileRef method)
		have AddFileRef(dwarf.Sym, interface {})
		want AddFileRef(dwarf.Sym, interface {})
src/cmd/internal/obj/dwarf.go:80:20: cannot use dctxt (type dwCtxt) as type dwarf.Context in argument to dwarf.Uleb128put:

The failure started at 78baea8 (internal/bytealg: add assembly implementation of Compare / CompareString on mips64x), which seems unrelated.

cc @mengzhuo as builder owner and author of that commit
cc @jeremyfaller @aclements for runtime and dwarf

My bad.
Will look into it.

Seems like this was fixed?
