[svn-r27653] Merge of r27645 from the autotools branch.

Updates to older special config files in configure.ac:

- solaris2.x renamed to solaris. There are recent changes to this file
  but the "2.x" is misleading since the changes are applied to all
  versions.

- Removed support for OSF 4.x/5.x (Digital and Tru64 Unix). We no
  longer have the config files for these.


Tested on: h5committest
