Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

Even when doing static builds, a shared library is built. This causes a
build failure under some circumstances, for instance when building for
MIPS + uClibc + static.
After asking upstream if it would be possible to add a configure option
to not build the shared library, the answer was that doing a static
build is not a good idea. Here is a small snippet of the conversation:
"Note that fully static builds are problematic. elfutils uses dlopen to
open the EBL backends (the CPU-specific support snippets), so even if
you link statically, the final binaries are still considerably dynamic."

The elfutils package provides a more recent version of the libelf, so
let's use it. It will allow to remove the libelf package and to avoid
conflicts with two packages providing the same library.

Kexec-lite is a tiny impementation of kexec for devicetree-based
platforms.
[Thomas:
- Add !BR2_PREFER_STATIC_LIB dependency, inherited from the dtc
package
- Fix license to be GPLv2+, and not just GPL.
- Use $(TARGET_CONFIGURE_OPTS) instead of manually passing CC, LD,
CFLAGS.
- Use a full path as the target of $(INSTALL)]
