* Makefile (distribute): Add it. * Makerules ($(objpfx)%.dynsym, $(objpfx)%.symlist): New rules. (tests): Depend on .symlist file for each $(install-lib.so-versioned). [! subdir] (tests): Depend on libc.symlist. (generated): Add those files. * aclocal.m4 (LIBC_PROG_BINUTILS): Check for objdump, set OBJDUMP. * configure: Regenerated. * config.make.in (OBJDUMP): New variable, substituted by configure. * malloc/mcheck.c (struct hdr): New members `block' and `magic2'. (mallochook, reallochook): Set them up. (checkhdr): Check HDR->magic2 value. (freehook): Reset HDR->magic2. (memalignhook): New static function. (old_memalign_hook): New static variable. (mcheck, reallochook): Set __memalign_hook to memalignhook.
