            Bug ID: 65176
           Summary: config.guess failed to guess machine with 64-bit
                    kernel and 32-bit user space:
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com

Depending on "uname -m" doesn't work with 64-bit kernel and 32-bit
user space:

bash-4.3# uname -m
x86_64
bash-4.3# gcc -v
Using built-in specs.

I am expecting i686-unknown-linux-gnu, not x86_64-unknown-linux-gnu.
