Hmmmm. AFAIK the way it works now on linux is that if "uname -m" gives
i?86 then ARCH is set to i686. Allowing an incoming ARCH==i586 would
seem to be complicating things.
But yes it is quite insane now. For 32-bit x86 we have:
LIBARCH=i386 (used for: jre/lib/i386)
BUILDARCH=i486 (used eg for:
PLATFORM=<os>_i586 (used for runtime images and bundles)
and in fact it is even more complex as solaris, linux and windows differ
in the variables they use.
Don't know how this came about ... it's not like we use UltraI, UltraII,
UltraIII etc for sparc. Probably something legacy from the original
