* 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.
