Check for RELEASE-NOTES file; locale specific extension doesn't exist

[Ray Van Dolson <rvandolson esri com>]

Hi all, noticed the following when doing an "askmethod" install of
CentOS 5.0.  I'm not sure if it's truly an anaconda related issue, but
figured this would be a good place to start.

Basically, if I do an http method installation, the installer looks for
the following files on my web server:

  RELEASE-NOTES-en_US.UTF-8.html
  RELEASE-NOTES-en_US.UTF-8
  RELEASE-NOTES-en_US.html
  RELEASE-NOTES-en_US

However, on my CentOS 5.0 CD, the only files present are:

  RELEASE-NOTES-en.html
  RELEASE-NOTES-en

Obviously, it's trivial to create a symlink or something to fix this,
but is there a better way to address this?  Should CentOS be providing
one of the above files, or should anaconda be requesting one of the
lower two filenames instead?

Maybe I can just override my locale (LANG) settings somewhere before
this step.

Any insight appreciated,
Ray
