[5/5] kmod: does not support static builds

Since kmod 14, the support for building a static library has been
removed completely from kmod. Therefore, we mark kmod as
!BR2_PREFER_STATIC_LIB, as well as all its reverse dependencies, which
includes the option to use the "udev" /dev management method.

I agree.

No because the default is --enable-static --enable-shared, and the
configure script of kmod bails out with an error when --enable-static
is passed.

The dependency between udev handling and !BR2_PREFER_STATIC_LIB isn't
directly obvious to users, so I've added a comment - Similar to how we
do it for toolchain options.

Committed with that added, thanks.
