[PATCH 7/7] selftests/sparc64: report failures of the drivers subdirectory

[Sasha Levin <sashal@kernel.org>]

The sparc64 suite builds and installs its subdirectories in shell loops
whose status is that of the last command. For the build that is the
copy of the subdirectory's test script, so "make all" succeeds even
when the drivers tests fail to compile, and FORCE_TARGETS has no effect.

Fold the copy into the status of the subdirectory and let both loops
return failure when no subdirectory succeeds, which matches how the
top-level selftests Makefile treats its targets, or as soon as one fails
when FORCE_TARGETS is set. When a build report is requested, record
each subdirectory as sparc64/<subdir>. Invoke the subdirectories with
$(MAKE) so that they use the parent's jobserver.

Fixes: 3c545084130c ("selftests: sparc64: char: Selftest for privileged ADI driver")
