Subzero makefile changes for linking a static llvm2ice nexe w/ LLVM build sys.

Need to list more dependencies, otherwise the static
link fails. The current unsandboxed build is a shared build
which uses libLLVM-3.*.so.

Also mess with the CXXFlags a bit. The current pnacl-llc
nexe build uses O3, but that triggers a method pointer bug:
https://code.google.com/p/nativeclient/issues/detail?id=3857,
so override that with O2. We may just want to change the
pnacl-llc build as well (maybe use Os), but I don't
know of the performance implications right now.

Use gnu++11, because of newlib + libc++.

Toggle the feature flags to be a MINIMAL build when
building the sandboxed translator w/ the LLVM-based
Makefile.
