[PATCH v2 5/5] Makefile: don't "rm configure" before generating it

Remove a "rm configure" before we make a new "configure" file via a
"configure+" temporary file. This was partially made redundant via the
new ".DELETE_ON_ERROR" target.

"Partially" because if we die partway we'll remove the "configure"
now, but as before we'll leave the "configure.ac+" in place. Ideally
we'd have another target for the "configure.ac+" so this would all
work properly, but due to the logic added in 122650457a6 (build: do
not automatically reconfigure unless configure.ac changed, 2013-01-02)
that's non-trivial to untangle.
