scc-cpp.sh and gcc-scc.sh: improve handling of arguments

Previously, any argument to scc-cpp.sh and some arguments to gcc-scc.sh
were broken if they contained any IFS chars, such as space.

Now correct quoting is used in these scripts, which do maintain the
arguments correctly.

In scc-cpp.sh the change is trivial from $@ to "$@" .

In gcc-scc.sh it's a bit more involved as arguments are handled
individually and iteratively.

The big change is replacing .c with .o for all file names for $ld,
where instead of converting the whole line in one sed, we now iterate
the files individually while maintaining any IFS chars in them
