Backport #975 from trunk:
Warn the user if he/she recalls a sample with EXPERIMENTAL features.
Also, print the EXPERIMENTAL status when listing the samples.

NB: even it is not purely a fix backport, it is still very important that the user gets warned about the EXPERIMENTAL status of the samples.

 Glibc does not build: asm/page.h not found

 As of linux-2.6.25, asm/page.h is no longer exported.

 This means the glibc up to and including 2.6 will not build against headers

 exported from linux-2.6.25 and up. Starting with glibc-2.6.1, patches are

 available that solves the issue. Switch to at least 2.6.1 if you can, or try

 to backport the fix (should be quite easy).
