In this case of libc, it's usually a good idea to do the full 
buildworld, since libc gets statically linked into various toolchain 
binaries.  Fortunately, this bug in malloc only affects multi-threaded 
applications; otherwise you'd have an unrecoverable system (though I 
would have noticed that before committing).
