* sysdeps/unix/sysv/linux/init-first.c (init): Remove [! SHARED] conditional from __libc_multiple_libcs access. Remove kludge for weak symbol access with old compilers we no longer support. * sysdeps/unix/sysv/aix/init-first.c (init): Likewise. * sysdeps/generic/libc-start.c (__libc_start_main): Likewise.
