Rafael Espindola 708bc15ff0 Require python 2.7. 
We were already requiring 2.5, which meant that people on old linux distros
had to upgrade anyway.

Requiring python 2.6 will make supporting 3.X easier as we can use the 3.X
exception syntax.

According to the discussion on llvmdev, there is not much value is requiring
just 2.6, we may as well just require 2.7.

Upgrading autoconf
===============================================================================

If you are in the mood to upgrade autoconf, you should:

 1. Consider not upgrading.
 2. No really, this is a hassle, you don't want to do it.
 3. Get the new version of autoconf and put it in <SRC>
 4. configure/build/install autoconf with --prefix=<PFX>
 5. Run autoupdate on all the m4 macros in llvm/autoconf/m4
 6. Run autoupdate on llvm/autoconf/configure.ac
 7. Regenerate configure script with AutoRegen.sh
 8. If there are any warnings from AutoRegen.sh, fix them and go to step 7.
 9. Test, test, test.
