Update all samples to the latest set of options.

Update some samples to use newer features.
Add patches for the uClibc-20080801 snapshot to be able to build with gcc-4.3.
Add a patch against glibc-2.7 to allow building PPC with latest kernel headers.
Add a patch to gcc to use an alternate unwinding when built against uClibc (after a private explanation/request by Daniel Egger <daniel@eggers-club.de>)
