Michael Frysinger 991addc261 MAINTAINERS: clarify policy with config/ (and other top level files)
Rather than copy & paste more text, just merge the existing config/
section with the existing intl/ section.  This ends up clarifying
the policy with that subdir (and top level files) that any commit
made to gcc's repo is allowed to be merged with the sourceware tree
without pre-approval.

Christopher Faylor 28c8ae66d5 * fhandler.h (PIPE_ADD_PID): Define new flag.
* pipe.cc (fhandler_pipe::create): Don't indiscriminately add process id to
every pipe since some pipe names (fifo, tty) don't need it.
* sigproc.cc (sigproc_init): Pass PIPE_ADD_PID to fhandler_pipe::create to
ensure that pid is always part of sigwait pipe name.
