checksum-freshness: Fix invalid checksum calculation for binary files
Admittedly this is not the cleanest way to achieve this, but SourceMap is quite intertwined with source files being represented as Strings.

The run-make test suite contains tests which are the most flexible out of all the rust-lang/rust test suites. run-make tests can basically contain arbitrary code, and are supported by the run_make_support library.
Infrastructure
A run-make test is a test recipe source file rmake.rs accompanied by its parent directory (e.g. tests/run-make/foo/rmake.rs is the foorun-make test).
The setup for the rmake.rs can be summarized as a 3-stage process:
First, we build the run_make_support library in bootstrap as a tool lib.
Then, we compile the rmake.rs "recipe" linking the support library and its dependencies in, and provide a bunch of env vars. We setup a directory structure within build/<target>/test/run-make/
<test-name>/
rmake.exe # recipe binary
rmake_out/ # sources from test sources copied over
and copy non-rmake.rs input support files over to rmake_out/. The support library is made available as an extern prelude.
Finally, we run the recipe binary and set rmake_out/ as the working directory.
