Among the standard rust libs, libtest depends on libstd:
https://github.com/rust-lang/rust/blob/master/library/test/Cargo.toml#L12
The current implementation was adding it to
between_core_and_std_files
. This may cause backward reference linkererrors in some configurations where the linker is configured to check
for such backward references and the toolchain uses the static version
of libtest.
