* utils.c (prompt_for_continue): Reinitialize more-counts

before printing anything, and again afterward.  Fix comments.
(vfprintf_filtered):  Eliminate static buffer; use auto buffer,
or alloca() if needed.

* rs6000-xdep.c:  Use correct conditional (IBM6000_TARGET) to
detect native versus cross-host.
