[Slackbuilds-users] qemu annotations

Hello there,

I've had a closer look at the qemu SlackBuild and now I'm wondering about 
some of the constructs in there.

The checks for libusb, spice and usbredir seem to be completely redundant 
because qemu's configure will check for availability of these features and 
enable them when possible.

The check for the device tree compiler seems to be even more than 
redundant, because this isn't even an optional depedency as the dtc has 
been bundled with qemu since at least version 2.0.0.

Most configure options just state the defaults.

The OS_CFLAGS parameter is probably meaningless; it's not used anywhere in 
the makefiles.

A propos make... to get a parallel build (e.g. with MAKEFLAGS=-j4) you 
have to "make config-all-devices.mak config-all-disas.mak" first, 
otherwise "make" will run a single job only which will take quite a while 
when building all targets (anybody with a better understanding of "make" 
care to explain?).

Maybe the qemu SlackBuild should get a cleanup (and an update to 2.1.2).
