* sysdeps/unix/sysv/linux/hppa/sysdep.h: Fix merge error.
2003-10-15  Roland McGrath  <roland@redhat.com>

	* elf/dl-iteratephdr.c [! SHARED] (dl_iterate_phdr): New function.
	Fake an entry for the main executable and then call __dl_iterate_phdr.
	* elf/Makefile (routines): Remove dl-iteratephdr-static.
	(elide-routines.os): Likewise.
	(CFLAGS-dl-iterate-phdr-static.c): Variable removed.
	* sysdeps/generic/dl-iteratephdr-static.c: File removed.
	* sysdeps/unix/sysv/linux/ia64/dl-iteratephdr-static.c: File removed.
