[kvm-unit-tests PATCH] riscv: lib: Add sbi-exit-code to configure and environment

Thu Jul 3 06:36:00 PDT 2025
Add --[enable|disable]-sbi-exit-code to configure script.
With the default value disabled.
Add a check for SBI_PASS_EXIT_CODE in the environment, so that passing
of the test status is configurable from both the
environment and the configure script
