   5 # selecting the big endian ABI and if they are then
   6 # we set libc_cv_aarch64_be to yes which causes
   7 # HAVE_AARCH64_BE to be defined in config.h and
   8 # in include/libc-symbols.h and thus available to
   9 # shlib-versions to select the appropriate name for
  10 # the dynamic linker via %ifdef.
