bazel: Allow multiple definitions for armeabi android links

When working on rust support we hit this issue rust-lang/compiler-builtins#353 which seems to still be persistent even in the case you have the nightly version mentioned there. I haven't been able to reproduce the issue in a separate project, but the core seems to be that both libgcc and rust's compiler builtins module vendor some float math symbols and both are included. This change is as scoped as possible so that no real issues could sneak in with this disabled, which should mostly be covered by only passing this for the single arch.
