V4:
	- Definitely update to use __base_sbi_ecall
V3:
	- Update to use __base_sbi_ecall (also fixes the correct paramenters)
	- Rename env var to IMPL_ID to match the other tests
V2:
	- Update commit description to fit 70 chars
	- Move sbi_ecall() after expected assignment to make consistent with
	  other tests
