make: remove unnecessary words from command line options

Several years ago, the command line options were individual global
variables.  The global variable could therefore not be named 'silent'
since that would have conflicted with local variables of the same name.
After moving the global variable to the namespace 'struct CmdOpts',
there is no conflict anymore.

There doesn't seem to be any risk of naming collisions for the names
'touch' and 'query'.

No functional change.
