RFR: 8151630 and 8151631 ios build failures after b106 merge

[Gary Adams]

A minor problem arises when we eliminate the last cmd from the ios build.
When making images the support/modules_cmds-stripped is passed to the
jimage tool, but the directory is not created if no cmds were processed.

This will be a moot issue once the jigsaw integration is complete. In 
the interim,
here is a workaround I'd like to add that gets past the problem.
