 A legitimate use of `-optl` and `-optc` is to pass options that should
 ''always'' be passed to gcc, such as `-B<something>` if we're invoking
 `gcc` against a particular set of libraries.  For this to work, we have to
 ensure that `-optl` and `-optc` options are always passed.

 In `joinObjectFiles`, we don't add the options from `-optl`.  I suspect
 that we don't want to just add them, because we also put the `-l` options
 in this list, so we should separate the two.

 In `mkExtraObj`, we don't add the options from `-optc`.

 Probably we should refactor things so that these options are automatically
 added by `SysTools.runCc` and friends, being careful about option
 ordering.
