[Bug libc/9854] glibc opens up new tty to print *** %n in writable segment detected ***

glibc attempts to write to the controlling terminal, in the hopes that it will
be noticed at the highest possible level.  Especially since a process may have
closed its stderr already.

To explicitly disable this and try to write to fd 2, you can set the environment
variable LIBC_FATAL_STDERR_=1 (yes, there is a trailing underscore in the
variable name).
