* elf/ldconfig.c (add_dir): Move logic to add entry to list to new
function add_single_dir.
(add_single_dir): New function.
(search_dir): Use add_single_dir instead of recursing.
* sysdeps/generic/dl-cache.h: Include stdint.h.
(struct file_entry_new): Use fixed sizes for interoperability
between 32bit and 64bit systems, add __unused to make alignment
