Update to 0.14.4:

Fixed a bug in the MULTIBOOT case with kernels like GENERIC.MPACPI.
These kind of kernels do not define "options MULTIBOOT" because
they include another config file that has defined the option.

Rather than using grep -q MULTIBOOT on the kernel config file,
use config(1) -x <kernel> and check if MULTIBOOT is set.
