POSIX leaves undefined the order of output if stderr is injected into stdout,
and in practice it differs on Windows (Linux buffers both streams separately,
Windows interleaves them as they arrive without buffering).
This should help testing on other platforms
The tests are not exhaustive, there are some conditions that aren't
checked. The tests are based in the C standard rules about undefined
behaviour.
This is a compatibility break but, hopefully, all projects are using
sane values. If not, there is no guarantee that the projects will build
in any platform where RGBDS can be compiled, so it would be better to
fix them.
Even though, technically, the left shift of a negative value is always
undefined, some projects rely on its current behaviour. This is the
reason why this doesn't cause a fatal error.

Due to recent changes, lots of tests generated a slightly different
error output.
- bank-noexist : This test doesn't generate any error output now as
unknown labels are left for the linker to resolve.
- null-in-macro : This test used to crash. Now, the parser verifies that
a MACRO ends in ENDM, generating an error message if not.
