Add a new option --no-checks to kexec that allows for a fast
reboot by avoiding the purgatory integrity checks. This option is
intended for use by kexec based bootloaders that load a new
image and then immediately transfer control to it.

For s390 we first want to check if kdump checksums are valid before we start
the kdump kernel. With this patch on s390 the purgatory entry point is
called with a parameter. If the parameter is "0", only the checksum test
is done and the result (0 = ok, 1 = invalid) is passed as return code back
to the caller (kernel). If the parameter is "1", the complete purgatory code
is executed and kdump is started.

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.

o Moved kexec_flags inside kexec_info structure.
