-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.
