description:
Correct temporary directory preference order in libiberty's choose_tmpdir().

Because it is intended to be persistent, /var/tmp is about the worst possible
choice for temporary files for most users of libiberty.  /tmp works better,
because the the defined semantics of /tmp allow for a non-persistent tmpfs
to be used.  This should improve performance when /tmp is a tmpfs and it is
difficult or impossible to have an environment variable or command line -pipe
flag passed to every piece of the toolchain.
