[PATCH 3/5] newlib: phoenix: merge machine/ trampoline up a level

The machine/{configure,Makefile} files exist only to fan out to the
specific machine/$arch/ subdir.  We already have all that same info
in the phoenix/ dir itself, so by moving the recursive configure and
make calls into it, we can cut off this logic entirely and save the
overhead.
