instead of _dl_loaded.

(dl_main): Set _dl_rtld_map.l_type to lt_library.

dependencies loaded, downgrading lt_executable -> lt_library.

* elf/dl-deps.c (_dl_map_object_deps): Use a linked list of alloca'd
elements and then scan it to fill the single malloc'd array, instead
of using realloc to grow the array in the first pass. _dl_map_object
may do some mallocs that break our stream of reallocs, and the minimal
realloc can't handle that.

putting dup elts in search list.
* elf/dlclose.c: Use MAP->l_searchlist to find deps to close.
* elf/dlsym.c: Don't tweak linked list. Scope array given to
_dl_lookup_symbol does the right thing.

* sysdeps/generic/machine-gmon.h: New file.
* gmon/Makefile (distribute): Add machine-gmon.h.
