... where operating systems other than MacOS X, Solaris and !OpenSolaris
means Linux, since we currently don't support any other. And it doesn't
make any sense to mess with `SAGE64` and flag files on systems not
defaulting to 64-bit builds, unless or until we also support the opposite,
32-bit builds on systems that default to 64-bit.
As we support more OSs, it's trivial to add them to `sage-check-64`.

Because of its bad name, people erroneously set `SAGE64` in the past.
> Anyone using using something other than Linux, Solaris or OS X gets a
message that the system in unsupported.
Which is pretty correct.

to hold their hand any more.

Btw, one can configure GCC to default to 32-bit builds on (almost) any
system. (And one could configure GCC to default to 64-bit builds on e.g.
Solaris as well.)
