Neither.

I meant that you would pack two John binaries per tarball.  Please take
a look at the official Windows build of 1.7.9 - it has john.exe and
john-omp.exe.  You would similarly have john and john-omp inside the run
directory in your tarball.  And you would have two tarballs: for 32-bit
and 64-bit separately.  Oh, and another two for jumbo vs. not.

So 8 binaries total, but four tarballs total.  Two binaries per tarball.

For the filenames, call them:

john-1.7.9-Linux-x86-32-2.tar.gz
john-1.7.9-Linux-x86-64-2.tar.gz
john-1.7.9-jumbo-5-Linux-x86-32-2.tar.gz
john-1.7.9-jumbo-5-Linux-x86-64-2.tar.gz

with "-2" indicating your second build of these same versions.

No.  You should use the i-suffixed targets whenever possible, but you
should not include "i" in the tarball filenames.  Also no need to
include "omp" there because the same tarballs will have both binaries.

Yes.

(Some people will also want AVX and XOP builds, but let's not add this
complication to your builds yet, or you'd have to provide 24 binaries -
and that's ignoring MMX and older.)
