ldconfig: support hints files of either byte-order
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.
