tools/testing/selftests: add self-test for verifying load alignment This produces a PIE binary with a variety of p_align requirements, suitable for verifying that the load address meets that alignment requirement.

selftests/exec: Build both static and non-static load_address tests After commit 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error"), the load address alignment tests tried to build statically. This was silently ignored in some cases. However, after attempting to further fix the build by switching to "-static-pie", the test started failing. This appears to be due to non-PT_INTERP ET_DYN execs ("static PIE") not doing alignment correctly, which remains unfixed[1]. See commit aeb7923733d1 ("revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"") for more details. Provide rules to build both static and non-static PIE binaries, improve debug reporting, and perform several test steps instead of a single all-or-nothing test. However, do not actually enable static-pie tests; alignment specification is only supported for ET_DYN with PT_INTERP ("regular PIE").

selftests: complete kselftest include centralization This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

This appears to be due to non-PT_INTERP ET_DYN execs ("static PIE") not doing alignment correctly, which remains unfixed[1]. See commit aeb7923733d1 ("revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"") for more details. Provide rules to build both static and non-static PIE binaries, improve debug reporting, and perform several test steps instead of a single all-or-nothing test. However, do not actually enable static-pie tests; alignment specification is only supported for ET_DYN with PT_INTERP ("regular PIE").
