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.

    10 

    11 On sh[34]-linux, memset function does not work if 2nd argument is negative

    12 and 3rd argument is greater than 12.

    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.

    14  

    15 Attached patch fixes this problem.

    16  

    17 	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
