c0934e1eca Auto merge of #1152 - divergentdave:shim-directory, r=RalfJung 
Add directory-related shims

This PR adds support for `mkdir`, `rmdir`, `opendir`, `closedir`, and `readdir64_r`.

Open directory streams are tracked through a HashMap indexed by pointer locations, which holds directory iterators. Since `DIR` is an opaque type in glibc, I represent them with 1-byte allocations, and then just use their pointers in HashMap lookups.

Tests are included to exercise the new functionality.

e530829797 Use 'cargo check' to build the sysroot and target crate 
Fixes #1057

Since we are no longer using "cargo rustc", we now use the rustc
arguments passed by Cargo to determine whether we are building a
build dependency, normal dependency, or "target" (final binary or test)
crate.

Add shim for rename

This adds a straightforward shim for rename, which is used by `std::fs::rename`. Testing is included.

As a heads up, I expect one or two merge conflicts between my PRs, since some of them touch the same `use` statements, or add items near the same places. I'll rebase and fix them as they come up.
