Comment:

 After looking at this issue, it seems that:
 - `signmar` is the same as `mar` with some additional features. So if we
 need a 32 bit `mar`, we could probably use `signmar`.
 - we can use this patch to build `mbsdiff` for linux32:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 build.git/tree/projects/firefox/mbsdiff.patch?h=bug_31449_v3

 However it seems that the only place where `mbsdiff` is used is for
 generating incremental mar files, which we usually do on a 64bit machine,
 so I'm not sure we need a 32bit `mbsdiff`. It seems also that our signing
 script is only using `signmar` and not `mar`. Is there an other reason
 that I'm forgetting for wanting 32bit versions of `mbsdiff` and `mar`?
