META_MODE: Avoid command changing in 2nd build.

If the command to be ran changes then a rebuild is caused. Checking
exists(${DESTDIR}...) from make results in this on the 2nd and
possibly subsequent builds due to staging during build.  Avoid this
by always running the existence check in the make sh command.
