Dan, when I firstly read this bug, I thought it was request for syncing 
config.{guess,sub} with gnuconfig upstream.  But apparently, this issue is not
fixed upstream yet?

Well, I am a bit confused too :-)

[root@ibm-power7r2-01-le02 ~]# cat /etc/fedora-release 
Fedora release 21 (Twenty One)
[root@ibm-power7r2-01-le02 ~]# rpm -q automake
automake-1.14.1-4.fc21.noarch
[root@ibm-power7r2-01-le02 ~]# /usr/share/automake-1.14/config.guess
powerpc64le-unknown-linux-gnu
[sharkcz@ibm-power7r2-02-le02 ~]$ /usr/share/automake-1.14/config.guess -v
GNU config.guess (2013-11-29)


the RHEL 7.0 automake also understands ppc64le and I don't see any LE specific patches

[sharkcz@ibm-power7r2-01-le01 ~]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.0 (Maipo)
[sharkcz@ibm-power7r2-01-le01 ~]$ rpm -q automake
automake-1.13.4-3.bs3.noarch
[sharkcz@ibm-power7r2-01-le01 ~]$ /usr/share/automake-1.13/config.guess 
powerpc64le-unknown-linux-gnu
[sharkcz@ibm-power7r2-01-le01 ~]$ /usr/share/automake-1.13/config.guess -v
GNU config.guess (2013-06-10)


but with config.guess extracted from automake-1.13.4-5.fc20.noarch.rpm I get
[sharkcz@ibm-power7r2-01-le01 ~]$ ./config.guess -v
GNU config.guess (2012-12-29)

Thanks for details, that is my mistake :( - the macro %configure in comment
made the config.guess replacement with (those days) obsoleted config.* from
redhat-rpm-config.

Yep, that makes this request clear.  I updated the config.{guess,sub} to
upstream git-HEAD as is encouraged by upstream anyway, should work for you
also.  I'll make bodhi update once automake-1.13.4-6.fc20 becomes built.
