+Subject: [PATCH] Add `RUSTC_SRC_PROVIDED` for sandboxed installs
+
+Allows package managers to provide an extracted rustc
+source to patch and build against. This effictively no-ops
+the fetch and unpack steps of minicargo.mk entirely, and
+adds some sanity checks to ensure that `RUSTCSRC` comes
+from the environment and contains a `Cargo.toml`.
+
+we also add a `/` after every `$(RUSTCSRC)` path fragment
+just in case the path from the environment does not have one.
