Introduce the notion of a 'sample comment'.

- presence of the sample's reported.by file is now mandatory.
- when saving a sample, reporter name & URL are queried, to avoid operator forget about creating the reported.by file.
- when saving a sample, one can store a few-liner comment.
- when recalling a sample, the reporter name, URL and comment (if present) are printed.
- update the powerpc-e500v2-linux-gnuspe sample to include Nate's comment (from his original mail).
- update all samples that were missing the reported.by file.

reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g.,

MPC8548, MPC8572).  It uses eglibc (for e500/SPE patches) and a recent

gcc (4.3.1, for e500v2 DPFP support) and will generate appropriate

dual-precision floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to

make sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE

ABI/instructions from getting into the kernel (which is currently

unsupported).  At this time, the kernel build system only passes

-mno-spe by default (this should be fixed soon hopefully).

A binutils snapshot is used to fix a bug present in 2.18 preventing

U-Boot from being compiled (CodeSourcery issue #2297: internal.h

(ELF_IS_SECTION_IN_SEGMENT): Adjust to cope with segments at the end of

memory)."
