Make the ldconfig program accept hints files in little-endian and big-endian format on all architectures. The default format is the native byte-order of the respective host. This is expected to change when a version of the pkg command is available that implements support for either byte-order in its internal ldconfig function. (Already committed in the development tree of the pkg utility, a release is expected at the end of Q1/2024). This update adds the -B option to the ldconfig program. It enforces the creation of a big-endian hints file on a little-endian host. The main purpose to is support of tests with non-native byte-order files on little-endian hosts. It will be removed when all supported FreeBSD releases use little-endian hints files by default. When little-endian hints files are generally used, support of either byte-order in libexec/rtld can also be removed. When support for big-endian hints files is no longer required, the COND_SWAP macro in ldconfig and rtld shall be replaced by le32toh(), which just return their argument on little-endian architectures.
