RFR: JDK-8160334: Building --with-parfait= fails with No rule to make target 'PARFAIT_NATIVEJMOD

[Tim Bell]

Erik:

> When building using a special Oracle internal tool, the value of the 
> JMOD_CMD variable has an environment variable assignment added to it 
> (SOMETHING_FOO=foo /path/to/jmod). This causes the build to break in 
> jmod creation, because the value of JMOD_CMD is used as a prerequisite 
> in a rule declaration. This patch adds a wildcard to filter out any 
> non files from the variable JMOD_CMD before trying to use the value as 
> a prerequisite.

OK - looks good to me.
