OK, I made emem provide allocations which are suitably aligned for SPARC in
r42407 and r42431, both of which I also scheduled for 1.6.8.

Interestingly I found that different versions of GCC and different optimization
levels provide different results; that's why I couldn't reproduce this crash on
my system.  Apparently sometimes GCC uses the 'std' and 'ldd' (which require
8-byte alignment) and sometimes it doesn't.

That also meant I couldn't write a C program (for configure to run) which would
reliably determine if we needed 8-byte alignment.  So the code now just assumes
all non-i386 CPUs need 8-byte alignment.
