gcc-scc.sh: parse options using getopts

Previously, the options parsing code rejected some valid inputs,
such as -ofile (in one arg).

Now we use standarg getopts which conforms to the POSIX syntax
guidelines.

Additionally, improve the error message on unknown option:
- print to stderr instead of stdout.
- quote it (otherwise these are globs...).
- Add spaces between the options (still less than 70 chars).
