config.gcc (*-*-netbsdelf*): Set up generic parameters.

* config.gcc (*-*-netbsdelf*): Set up generic parameters.
(*-*-netbsd*): Always use collect2.  Remove collect2 settings from
other non-elf netbsd config frags.
* config/netbsd-aout.h (STARTFILE_SPEC): Don't pull in c++rt0 since
collect2 will does that.
* config/netbsd.h (LIBGCC_SPEC): Add white space before -lgcc, so that
shared-lib frobbing will work.
