* sysdeps/generic/ldsodefs.h (_dl_load_lock): Declare it here with
__libc_lock_define_recursive. * elf/dl-open.c: Don't declare it here any more. * elf/dl-close.c: Likewise. * elf/dl-lookup.c: Likewise. * elf/dl-iteratephdr.c: Likewise. * elf/dl-lookup.c (add_dependency): Use __libc_lock_lock_recursive and __libc_lock_unlock_recursive. * elf/dl-close.c (_dl_close): Likewise * elf/dl-iteratephdr.c (__dl_iterate_phdr): Likewise * elf/dl-open.c (_dl_open): Likewise * sysdeps/generic/bits/libc-lock.h (__libc_lock_define_recursive): New macro. * sysdeps/generic/bits/stdio-lock.h (_IO_lock_t): Use it. (_IO_lock_lock): Use __libc_lock_lock_recursive. (_IO_lock_unlock): Use __libc_lock_unlock_recursive.
