Yah ... if you're running -current as of Sunday, you will need these
options.  If they're already in your port's std.foo file, you won't
need to add them to your specific config file...

The change is that code for the various exec types is no longer
unconditionally included; in the old world all port got a.out and script
support in the kernel... except for the pmax and alpha ports, which
overrode those defaults.

As NetBSD looks at other exec formats, a more flexible way of including
support for them will be needed (indeed, this was part of the reason
that the chage was made; the alpha port is transitioning from ECOFF
to ELF), and this provides it.
