parse_options: accept multiple arguments
Allow command-line options to accept multiple arguments without
additional quoting by taking the list of arguments until one
starting with a "-" is reached.
The only current use of this is the --pkg option in makepkg. This
allows (e.g.)
makepkg --pkg foo bar
and packages "foo" and "bar" will be built.
