selftests: add build/cross-build dependency check script
Add build/cross-build dependency check script kselftest_deps.sh
This script does the following:
Usage: ./kselftest_deps.sh -[p] <compiler> [test_name]
kselftest_deps.sh [-p] gcc
kselftest_deps.sh [-p] gcc vm
kselftest_deps.sh [-p] aarch64-linux-gnu-gcc
kselftest_deps.sh [-p] aarch64-linux-gnu-gcc vm
- Should be run in selftests directory in the kernel repo.
- Checks if Kselftests can be built/cross-built on a system.
- Parses all test/sub-test Makefile to find library dependencies.
- Runs compile test on a trivial C file with LDLIBS specified
in the test Makefiles to identify missing library dependencies.
- 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.
To make LDLIBS parsing easier
- change gpio and memfd Makefiles to use the same temporary variable used
to find and add libraries to LDLIBS.
- simlify LDLIBS append logic in intel_pstate/Makefile.
