 somebody on 32-bit x86 Debian Linux couldn't compile Sage due to an 
 outdated assembler not supporting the rep ret instruction which our 
 GCC-4.9.2 generates.

 According to
 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=gas/NEWS;hb=refs/tags/binutils-2_24
 one requires GNU assembler version 2.23 which isn't even in Debian unstable.

both Debian unstable and testing ship binutils version 2.24.
Do you mean to say they package old gas there?


 What should we do about this? Just document it? Ship our own version of 
 binutils?

 Jeroen.

Certainly they don't do this; on jessie they ship
GNU assembler version 2.24.90

I'd say just document; after all installing a newer binutils should not
be a problem on Debian, and it's for old hardware + one particular OS
flavour.
