Some applications do in fact use x86_64 instructions unconditionally,
which results in a couple of packages to fail compilation on i686, mips
and arm.  These are pretty easy to identify by looking at the build
logs.  For some of these scientific applications, upstream is not
interested in fixing the build failures as they only support x86_64.

On the other hand we have many more packages that cannot currently be
built because they depend on libraries or applications that fail on
i686, mips or arm.  I=E2=80=99m hoping to look at the icedtea and openbla=
s
failures on mips and arm on Sunday.
