[zeromq-dev] s390x support

At the moment I disable CONFIG_HAVE_RTC etc via the configure script in zeromq2 directory but I've a feeling I should be doing something a little more elegant. Do the Sconstruct files figure into this?

For PGM I think you should already be disabling RTC & HPET support for System Z it would therefore make sense to add TSC onto the list.

The only other assembly in the code is for atomic ops and GCC or Solaris intrinsics are the preferred option, inline code used for older GCC versions, i.e. Red Hat 4, and non-Solaris platforms, i.e. OpenSolaris.  I'm ignoring the add-with-carry inline functions as they're not used anywhere (impl/checksum.h).

So alongside IA64, PowerPC and ARM assembler which is sitting in an old revision in SVN history somewhere I will currently leave out System Z assembler unless performance testing results prove significant advantage *and* the transport is in production use.

Or, simply part of a contract porting project with full platform testing, :D
