Since we use the implicit ruls for .c and .S, just colelct all sources
in the one variable.

Purgatory seems to partially duplicate system headers.
It seems a log cleaner not to do so.

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.

[BUILD] Make sure sha256.c is compiled without optimisation
sha256.c needs to be compiled without optimization, else
purgatory fails to execute (on ia64 at least).
By placing -O0 after $(CFLAGS), which is provided by
the prevailing environment, it overrides any other -O flags
provided.

[BUILD] CPPFLAGS, CFLAGS and LDFLAGS fixes
* Set internal CPPFLAGS as EXTRA_CPPFLAGS, CFLAGS as EXTRA_CFLAGS,
and LDFLAGS as EXTRA_LDFLAGS
- Don't overwrite CPPFLAGS, LDLFAGS or CFLAGS from the environment
- They are irrelevant for BUILD_CC
- When cross-compiling for a ppc64 host on a non-ppc64 host,
EXTRA_CFLAGS, which is included in BUILD_CPPFLAGS contains
-mcall-aixdesc, which does not work on i386 at least
* Use LDFLAGS when linking kexec
- Append rather than overwrite in purgatory/Makefile
The purpose of these changes is three-fold.
* CPPFLAGS, CFLAGS and LDFLAGS from the environment really ought
to be honoured. For one thing;
* Without these changes, the confgiure taget in
the toplevel makefile can't work
* Without these changes, cross compiling does not work -
well, I can't work out how to get it to work anyway.
