Currently checks library dependencies. - Checks if Kselftests can be built/cross-built on a system running compile test on a trivial C file with LDLIBS specified for each individual test in their Makefiles. - Prints suggested target list for a system filtering out tests failed the build dependency check from the TARGETS in Selftests the main Makefile when optional -p is specified. - Prints pass/fail dependency check for each tests/sub-test. - Prints pass/fail targets and libraries. - Default: runs dependency checks on all tests. - Optional test name can be specified to check dependencies for it.
