I run 64x32 tests regularly here.
The way I do it is to hack site.exp to set host_triplet, etc. to i686-linux.
Done this way, nothing further is needed, in so far as handling
{32,64}-cross-{64,x32}.

[I'm leaving as a separate discussion whether we need to xfail these
for i686-linux too.  It passes here, but I gather it fails with more
recent glibc's]
