Is 'arch -k' universally supported on all platforms?

[Dr. David Kirkby]

I need to create a patch which is only applied on the sun4v
architecture. The way to test for that on Solaris is use use 'arch -k'

On 't2'

kirkby@t2:[~] $ arch -k
sun4v

On my own Sun Blade 2000

drkirkby@kestrel:[~] $ arch -k
sun4u

Is 'arch -k' supported on all platforms - linux, FreeBSD, OS X or
anything else we want Sage to work on?

I could test for Solaris first, then use 'arch -k' but if it's
universally implemented, then I'll do it in one step.

Debian GNU/Linux:

$ arch -k
arch: invalid option -- 'k'
Try `arch --help' for more information.
$ arch --help
Usage: arch [OPTION]...
Print machine architecture.

--help display this help and exit
--version output version information and exit

Not on Ubuntu, apparently it has been deprecated upstream (in Debian?):

https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/148511

They say to use "uname -m"

No problem, I'll test for Solaris first - something like:

if [ `uname` - "SunOS" ]; then
if [ `arch -k` = "sun4v" ] ; then
<do what I to do>
fi
fi

I was going to ask on AIX and HP-UX groups too, just in case someone
decided to port to one of those platform. But there is no point if its
not even supported on some linux distros.

Thank you. Under the circumstances, I think I'll test for Solaris first,
though 'uname -m' does in fact work on Solaris.
