Technically, this is seems to be a regression somewhere between 4.2 and
4.6 but, it seems, not enough for anyone to care too much. Tested on
various Darwin versions and x86_64, powerpc64 linux,
OK for trunk {now,stage1}?
thanks, Iain

For a regular compile job, with -v we emit the GCC version information
twice - once from main() and once from process_options(). We do not need
to emit the former unless the compiler will exit before calling
process_options(), which is controlled by the 'exit_after_options' flag.
Gating the first output on that flag resolves this.

gcc/ChangeLog:
* toplev.cc (toplev::main): Only print the version information from
the toplevel main() if we will exit before processing options.
