* llvm.spec.in: update blurb

* autoconf/AutoRegen.sh: use variables for autofoo versions
* autoconf/configure.ac: test for some more functions
                         that are not guaranteed on solaris

Note: the svn:mime-type of autoconf/AutoRegen.sh
      should be set to something that allows for
			text compares using svn diff
