Bugzilla Bug 69206

As pointed out in Bug 49662, the target for the main executable for qemu is
commented out in the ebuild to avoid screwing up compilations.  This is all
fine and dandy unless you don't know anything about qemu and are emerging it
for the first time.  Can we get an informational message that says something to
this sort?  

Thanks

Reproducible: Always
Steps to Reproduce:
1.  Emerge apps-emulation/qemu
2.  Search for qemu executable
3.  It's not there!

Actual Results:  
No qemu executable is found.

Expected Results:  
No qemu executable should be found.  However, the user should be
notified/reminded that the target for the executable has been commented out.

At least since version 0.6.0 the ebuild prints the following during postinst:

    use softmmu || \
    (
    ewarn "You have the softmmu useflag disabled."
    ewarn "In order to have the full system emulator (qemu) you have"
    ewarn "to emerge qemu again with the softmmu useflag enabled"
    )

As far as I see this solves this bug, please reopen if not.
