Patch from Bart Van Assche <bart.vanassche@gmail.com>:

The patch below implements the following changes:
- Make sure the output of the make command does not appear in the generated
  kernel patch.
- Changed interpreter of scripts/specialize-patch from /usr/bin/gawk to
  /usr/bin/awk in order to make sure this awk script also runs on systems
  where awk is installed but not gawk.
- Added an extra evaluation rule such that expressions like (0) are rewritten
  as 0.
- Fixed a spelling error.
- Expressions that can only be partially evaluated are now partially evaluated.
  E.g. #if defined(EXTRACHECKS) && (LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 18))
  becomes #if defined(EXTRACHECKS) && 0 in the output.
- Code between #if 0 / #endif or #if 1 / #endif is included in the generated
  kernel patch, including the surrounding preprocessor directives.
- Preprocessor statements with spaces behind # are now recognized (e.g. "#   if").
- Expression evaluator now supports ! (logical not) and () (braces).
- #elif is now evaluated correctly.
- Nested #if / #elif / #else / #endif are now interpreted correctly.
