[PATCH 1/3] selftests: ptrace build fails when invoked from kselftest target

[Shuah Khan]

ptrace Makefile doesn't have an explicit build rule. As a result,
ptrace build fails, when it is run from top level Makefile target
kselftest. Without the explicit rule, make works only when it is
run in the current directory or from selftests directory. Add an
explicit build rule to fix the problem.
