[PATCH v25 11/21] selftests/x86: Recurse into subdirectories

Jarkko Sakkinen
2020-02-04T06:07:02Z

Recurse into a list of subdirectories defined by SUBDIRS when running
x86 selftests. Override run_tests, install, emit_tests and clean
targets to implement this behaviour.

A possible alternative would be to add "x86/sgx" to TARGETS. However,
this would be problematic because detecting 64-bit build would have
to duplicated.

The implementation is derived from the makefiles of powerpc and sparc64
selftests.
