qtest: fix 'expression is always false' build failure in qtest_has_accel()
If KVM is disabled or not present, qtest library build may fail with: libqtest.c: In function 'qtest_has_accel': comparison of unsigned expression < 0 is always false [-Werror=type-limits] for (i = 0; i < ARRAY_SIZE(targets); i++) { due to empty 'targets' array. Fix it by making sure that CONFIG_KVM_TARGETS isn't empty. Fixes: e741aff0f43343 ("tests: qtest: add qtest_has_accel() to check if tested binary supports accelerator") Reported-by: Jason Andryuk <jandryuk@gmail.com> Suggested-by: "Michael S.
