Aha!  This is the issue I fixed for subdirectories on 2003-09-21.
I think we shouldn't "fix" this, but I'm open to comments; this
is one of the changes in autoconf we've been putting off.

Autoconf 2.13 used:

test "$host_alias" != "$target_alias" &&
  test "$program_prefix$program_suffix$program_transform_name" = \
    NONENONEs,x,x, &&
  program_prefix=${target_alias}-

While autoconf 2.59 uses:

# The aliases save the names the user supplied, while $host etc.
# will get canonicalized.
test -n "$target_alias" &&
  test "$program_prefix$program_suffix$program_transform_name" = \
    NONENONEs,x,x, &&
  program_prefix=${target_alias}-
