- The Makefile version *never* ran because of Makefile syntax confusion.
- The test would've always failed because precompiled std is not built
with `-Z cf-protection=branch`, but linkers require all input object
files to indicate IBT support in order to enable IBT for the
executable, which is not the case for std.
- Thus, the test input file is instead changed to a `no_std` + `no_core`
program.
