It picks up the suggestion for introducing enum opt_format in ldconfig. It also fixes a a ldconfig bug (wrong size in xmalloc call) uncovered by testing on i686-linux-gnu. I have dropped the s390x patch until I have located a suitable machine on which to test it. We also need to discuss how to achieve GCC alignment there. Patch order is different than before because both the x86_64 and powerpc64le patches contain tests now, including a test that runs the ld.so-based test without special options in the container, to check for ld.so.cache support. The powerpc64le patch aligns the subdirectory selection with GCC. I feel like this series has a reasonable level of test coverage. It does not test all possible permutations (ld.so option combinations and ld.so.cache contents), but I hope that's okay. (Not sure if this actually v4, I sort of lost count.)
