The .dependencies rule did not use the CPPFLAGS variable which led
to funny behavior: a spurious termination message the first time
(after checkout/make distclean) one executes make. Afterwards the
(wrongly) empty .dependencies file hides the problem and the binary
is created anyway.
$ make
cbmem.c:37:34: fatal error: boot/coreboot_tables.h: No such file or directory
compilation terminated.
cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86 -c -o cbmem.o cbmem.c
cc cbmem.o -o cbmem
$ make
make: Nothing to be done for `all'.
$ make clean
rm -f cbmem *.o *~
$ make
cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86 -c -o cbmem.o cbmem.c
cc cbmem.o -o cbmem
$ make distclean
rm -f cbmem *.o *~
rm -f .dependencies
$ make
cbmem.c:37:34: fatal error: boot/coreboot_tables.h: No such file or directory
compilation terminated.
cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86 -c -o cbmem.o cbmem.c

I fixed that by adding the CPPFLAGS variable to the .dependencies recipe, just
like Stefan Reinauer did in Chromium (Ia9d2e10a3ef122f30d681d16c2291eb108ead835),
hence the split sign-off for this tiny change. :)

Now users can use a different compiler from GCC like Clang by for example
doing `CC=clang make`.

The appropriate compiler (provided by the build system) is used to
ensure proper toolchain options are used.
cbmem.c is being modified to suppress pointer to integer typecast
warnings.

Coreboot and u-boot create a table of timestamps which allows to see
the boot process performance. The util/cbmem/cbmem.py script allows to
access the table after ChromeOS boots up and display its contents on
the console. The problem is that shipping images do not include Python
interpreter, so there is no way to access the table on a production
machine.
This change introduces a utility which is a Linux app displaying the
timestamp table. Conceivably the output of this utility might be
included in one of the ChromeOS :/system sections, so it was attempted
to write this procedure 'fail safe', namely reporting errors and not
continuing processing if something goes wrong.
Including of coreboot/src .h files will allow to keep the firmware
timestamp implementation and this utility in sync in the future.
Test:
. build the utility (run 'make' while in chroot in util/cbmem)
. copy `cbmem' and 'cbmem.py' to the target
. run both utilities (limiting cbmem.py output to 25 lines or so)
. observe that the generated tables are identical (modulo rounding
up of int division, resulting in 1 ns discrepancies in some
cases)
