3e8e24f2fc perf packaging: add memcpy to perf MANIFEST 
There seems to be a new dependency on arch/*/lib/memcpy*.S when compiling
the perf tool.  Make sure that file is included in the MANIFEST when
creating the tarball.

8e5564e6c7 perf tools: Make target to generate self contained source tarball 
Useful for when people want to try some version of the perf tools and don't
wants to download the kernel tarball.

Here is a session using this new target:

  [root@emilia linux-2.6-tip]# make perf-tarbz2-src-pkg
