Handle __gmon_start__ as undefined weak on hppa.
[BZ libc/19170] * sysdeps/hppa/crti.S: Declare PREINIT_FUNCTION weak_extern when PREINIT_FUNCTION_WEAK is nonzero. (gmon_initializer): New function. Put procedure label for it in .init_array section. (_init): Don't call PREINIT_FUNCTION. * sysdeps/hppa/crtn.S (__gmon_start__): Remove. * sysdeps/hppa/dl-lookupcfg.h (DL_FIXUP_MAKE_VALUE): Create null fixup value when map argument is null.
