[PATCH] make -f invalid when USE_SITECUSTOMIZE isn't set

[Steve Peters]

When you try running Perl-5.8.6 with a -f (which isn't valid), 
you'll see 
  > perl -f
  Unrecognized switch: -f  (-h will show valid options).

When currently running blead, Perl waits patiently for STDIN, 
even though not compiled to do site customization.  The 
following patch makes all the -f related code fully 
dependent on USE_SITECUSTOMIZE.  It also quiets a warning on
the noisy aCC compiler on HP-UX.
