The way tinytest was used in qemu-arm test target is that it didn't test much. MicroPython tests are based on matching the test output against reference output, but qemu-arm's implementation didn't do that, it effectively tested just that there was no exception during test execution. "upytesthelper" wrapper was introduce to fix it, so switch test implementation to use it. This requires passing different CFLAGS when building the firmware, so split out test-related parts to Makefile.test.

## With CoudeSourcery it's actually a little different, you just need `-T generic-m-hosted.ld`.

## Although for some reason `$(LD)` will not find that linker script, it works with `$(CC)`.

## It turns out that this is specific to CoudeSourcery, and ARM version of GCC ships something
