Hmmm, now we get ''"32-bit build, so writing 'no' to
SAGE_LOCAL/lib/sage-64.txt."'' on every non-OS X / non-[Open]Solaris
system...
(And if `SAGE64` is not set, we usually read the flag file twice.)

no need to give a warning on 64-bit Linuces.

You could check if {{{... `uname -m` in i[3456]86|ppc) ...}}}, Dave will
know what in addition to look for on [Open]Solaris (e.g. "x86") and
especially SPARC.
(On Darwin PPCs, `uname -m` might report more weird "processor names" like
"Power Macintosh", but that's IMHO a minor issue since the build would
fail later on 32-bit OSs anyway if we pass `-m64`. We do not support
64-bit builds on PowerPCs at all, so looking for
`i[3456]86|ppc*|[Pp]ower*` would be ok, too.)
----
If you edit `sage-check-64` again, you could remove the persistent
superfluous semicolon from `echo "SAGE_LOCAL undefined ... exiting";` ;-)
and replace {{{`uname`}}} by `"$UNAME"`.
