[Buildroot] [git commit] p7zip: new package

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=9bc2ba2169e087770680a0a21be0be267fb3070e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Only enabled on a subset of known-working architectures.
It fails to build on some archs, like blackfin.

Signed-off-by: André Hentschel <nerv at dawncrow.de>
[Thomas:
 - Add comment about the Blackfin exception.
 - Propagate the Blackfin exception to the Config.in comment.
 - Fix the license, it is the LGPLv2.1+ *with* the unRAR restriction.
 - Use $(INSTALL) -D -m 0755 to install the binary instead of cp.]
