gdb failing to build on RHEL 6

[Dave Kirby <dave.x.kirby@gmail.com>]

I am trying to build the latest version of gdb on RHEL 6, but it is
failing with the following error:

I have tried it with both the official 7.8.1 release from the ftp site
and the current head from the git repository - commit
8908fca5772fcff9f7766158ba2aa59f5a2b1f68.

I googled the error but all I found was a post on this forum from last
June with someone reporting the same problem
(http://sourceware.org/ml/gdb/2014-06/msg00007.html).  The only
response said there had been a broken commit, but no work-around was
given.  I find it hard to believe that it is the same issue and that
gdb has been released in a state where it would not build.

So what am I missing?  Or doing wrong?  Or is the release itself
broken?  How do I fix it and get a working build?
