I see exactly the same problem on i586-pc-linux-gnu, if I use "--prefix=~"
to configure the build.

I've never seen it said that --prefix=~ isn't allowed (although I can see
that if the arg is never interpreted by the shell it won't get expanded) so
is it supposed to work? If not, is there a way to prevent me from using it,
or to make it clear why the build has failed?
It works fine with --prefix=$HOME (obviously, as the shell expands $HOME
before configure sees the argument)
