Testsuite is done, results on [1], no change to prior run ([2]) - except
for the runtime, which went down by ca. 11 minutes and might be more
than just jitter.

As an extra, this version was also tested as cross-compiler, building
Linux v7.1-rc1 for real ia64 hardware and ia64 simulator. Worked well,
also the resulting kernel images:

e.g. on rx6600:
```
