config: Enable ACPI DEBUG FUNC trace.

pm-utils: The install program mangles install to be ../install

so do the same thing we did for directfb.

directfb: The install program gets somehow mangled to be ../../install

Fixed it by making in directfb a symlink to `which install` for install.

busybox: Config option did not have the applet turned off.

enable some more options: STACKPROTECTOR, IBFT, LOCKDEP, CPUFREQ

fix irqbalance deleting the /etc/service file.
