#     Revert "powerpc/64s: Remove support for ELFv1 little endian userspace"
#     
#     This reverts commit 606787fed7268feb256957872586370b56af697a.
#     
#     ELFv1 with LE has never been a thing, and people who try to make ELFv1 LE
#     binaries are maniacs who need to be stopped, but unfortunately there are
#     ELFv1 LE binaries out there in the wild.
#     
#     One such binary is the ppc64el (as Debian calls it) helper for
#     arch-test[0], a tool for detecting architectures that can be executed on a
#     given machine by means of attempting to execute helper binaries compiled
#     for each architecture and seeing which binaries succeed and fail. The
#     helpers are small snippets of assembly, and the ppc64el assembly doesn't
#     include the right directives to generate an ELFv2 binary.
#     
#     This results in arch-test incorrectly determining that a ppc64el kernel
#     can't execute a ppc64el userspace, which in turn means that a number of
#     developer tools such as debootstrap will break (assuming arch-test is
#     installed).
