userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@. With help from dlg@ and millert@.

Fixes endianess problems with old a.out tools. This makes building
some cross toolchains possible.

This also changes some utilities's behavior slightly:
- nm, strip, size now handle any a.out format they know about.
- ranlib complains if it detects mixed archives (several object
formats for different boxes).

In the presence of mixed objects, you still have file, ranlib or ld
to prevent you from getting too confused...
