[PATCH] be more robust when `make stage' fails

[Paolo Bonzini]

This patch avoids that the build goes on if `make stage' fails.  Thee 
`test -f && command || :' idiom is not ok if the command can fail, 
because in that case you won't notice when that happens.

This hid the other bug I'm sending a patch for, on CodeSourcery's 
testing system (reported by Dan and Joseph on IRC).
