package SFX stubs for other platforms

[Christian Pernegger]

When creating a self-extracting archive, a suitable executable stub is prepended to the archive proper. This stub is obviously platform-dependent. The default 7zCon.sfx (this package ships it in /usr/lib/p7zip) always matches the platform of the system p7zip is running on, i.e. the -sfx switch will create self-extracting archives for the same kind of system by default, which is reasonable.

However, the -sfx switch allows appending the name (interpreted relative to /usr/lib/p7zip) or the full path to the file that should be used for the stub, so one can easily create cross-platform self-extracting archives, too.

The only problem is, p7zip-full doesn't ship any alternative stubs. One has to download a version of 7-Zip for the target platform, extract the 7zCon.sfx file, and put it in /usr/lib/p7zip under a suitable name manually.

It'd be really nice if the p7zip-full package came with a selection of these as standard. And I believe this is something that could be done at the packaging level.
