Hi Matthias,

  I have no idea what is causing this. :-(

  If you look at the --help output of one of the built binutils tools, are any
32-bit x86 architectures listed, or just 64-bit ones ?

  Is it possible that there is a bug in how libgcc is testing for 32-bit x86
support ?  (ie could this be a libgcc bug rather than a binutils bug ?)

  This is so weird.  If it works for other hosts, why not the s390x ?  Could it
be an endian thing ?  The s390x is big-endian right, and all the rest are
little-endian ?

Cheers
