Ah, I didn't know this command existed. You never stop learning :-)

$ linux32 ./configure --prefix=$HOME
$ linux32 make
$ linux32 make check

gives

...
Native configuration is i686-pc-linux-gnu

So 'runtest' is indeed thinking it is running under a 32-bit system, but
'as' tries to assemble for 64 bits anyway.
I don't know whether that's a bug in 'as', or in Ubuntu, or just the way
'as' is supposed to work and the caller should determine the correct
options to use.
