With this change, I am able to build and test cross-platform rustc

In particular, I can use the following in my config.toml:

[build] host = ["i686-unknown-linux-gnu", "x86_64-unknown-linux-gnu"] target = ["i686-unknown-linux-gnu", "x86_64-unknown-linux-gnu"]

Before this change, my attempt to run the test suite would fail
because the error output differs depending on what your host and
targets are.

To be concrete, here are the actual messages one can observe:

% ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=x86_64-unknown-linux-gnu error: the type `std::option::Option<[u32; 35184372088831]>` is too big for the current architecture error: aborting due to previous error % ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=i686-unknown-linux-gnu error: the type `std::option::Option<[u32; 536870911]>` is too big for the current architecture error: aborting due to previous error % ./build/i686-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=i686-unknown-linux-gnu error: the type `std::option::Option<[u32; 536870911]>` is too big for the current architecture error: aborting due to previous error % ./build/i686-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=x86_64-unknown-linux-gnu error: the type `[u32; 35184372088831]` is too big for the current architecture error: aborting due to previous error

To address these variations, I changed the test to be more aggressive
in its normalization strategy. We cannot (and IMO should not)
guarantee that Option will appear in the error output here. So I
normalized both types Option<[u32; N]> and [u32; N] to just TYPE
