Build system simplification/standardisation
This change makes kexec-tools work more like a standard configure-make-
make-install-type project:
* Remove $(OBJDIR) stuff. To do an out-of-tree build, just configure
from a different directory.
* Use the implicit Makefile rules more, and just edit the compiler
flags for specific targets.
* Simplify compiler/linker flags - no need for EXTRA_*
* Add TARGET_CC, and improve checks for BUILD_CC too.
* Set arch-specific flags in arch-specific makefiles, not conditional
on $(ARCH).
* Generate dependency files in the main compile, rather than as a
separate step.
* Don't #include sha256.c, but re-build it into the purgatory.
Still a work-in-progress.
