The test_kexec_jump program builds correctly when invoked from the top-level selftests/Makefile, which explicitly sets the OUTPUT variable. However, building directly in tools/testing/selftests/kexec fails with:
make: *** No rule to make target '/test_kexec_jump', needed by 'test_kexec_jump.sh'. Stop.
This failure occurs because the Makefile rule relies on $(OUTPUT), which is undefined in direct builds.
Fix this by listing test_kexec_jump in TEST_GEN_PROGS, the standard way to declare generated test binaries in the kselftest framework. This ensures the binary is built regardless of invocation context and properly removed by make clean.
