char is always a byte, no need for a typedef. Section indices are

* elf/link.h (struct link_map): Replace l_deps_loaded flag member with
`struct link_map **l_searchlist' and `unsigned int l_nsearchlist'.
* elf/dl-lookup.c (_dl_lookup_symbol): Make SYMBOL_SCOPE arg an array
of two link_map ptrs. Search the maps in the l_searchlist of each
elt that is not null.
