The problem is that libiberty is a generic gnu library wrapping
software. I landed onto it from GDB.

I can see now that P_tmpdir was changed last year to /tmp.

OK. So the issue is understood. The problem will solve itself with some
time.

Meanwhile we could backport it to older branches and report to Darwin
people.

    move P_tmpdir from "/var/tmp/" to "/tmp/".

    the main effect of this is to make GCC and other libiberty using
    tools use /tmp instead of /var/tmp for compiler temp files,
    which can be a bottleneck on larger systems.

    a survey of other platforms shows only OSX also uses /var/tmp,
    everyone else has switched to /tmp long ago.


    cons:  some smaller systems may have a smaller /tmp than /var/tmp,
    and this may cause builds to fail with out of space earlier.
    point the build to /var/tmp using TMPDIR in this case.

    one can argue that setting TMPDIR would work around this, but we
    want to have the effect for all users without having special setup.
