The global pointer is used by some special assembly instructions
that we are not using (i.e., the compiler is not generating them
for us, because we don't use PIC or other "strange" stuff.

So, we'd better remove an assignement in the linker script that makes
little sense (it must be a typo of some kind, in the dark ages of this
code base).

We finally agreed to not use ptp-noposix any more. This allows simplifying
the main loop and library functions, in the future.

The previous version was compiled into a 64bit division
by gcc. in this way it uses no division, but a bitshift.

This reduces the compiled file by 4 bytes.

Some declaration was int8_t, some int32_t and some didn't match
the function definition. Now everything returns just int.
Anyway the functions return only 0 or -1, so there are no problems
returning int. Moreover in this way the resulting assembler is
smaller for every target architecture (even if here we always
build for lm32)

This reduces the binary by 30 bytes.

This adds 2.3kB to the GSI configuration, beause it enable ptpdump.
Earlier it was always forces off, due to wrong comparison of ram size.

By default the scb_ver is "33" but it can be modified at runtime in order
to load the config for SCB v3.4 (i.e, load-lm32 rt_cpu.elf scb_ver=34)

This cleans a little the calibrator code: we'll write to eeprom only
when the measured value is different from the previous one.

With this commit, code is also slightly smaller (28 bytes).

This includes ppsi-v2014.07.

The new ppsi master is Kconfig-based, so our makefile must
make "wrpc_defconfig" in ppsi before building it.
Additionally, the link steps changed to the better in there, so we
don't link the "strange" $(PPSI)/proto-standard/libstd.a any more.

We may consider whether a local .config for ppsi should be
provided by this package instead of relying on its own choices;
not a big deal, though, as we maintain them at the same time.

Please note that any existent ppsi/.config is preserved, to allow
local tests. This should not have any impact on normal users.

KERNELVERSION variable from Linux was still used.
It was not initialized so the displayed version in the headers
of make gconfig and make menuconfig was missingor wrong.
It just said (null) or KERNELVERSION.
KERNELVERSION has been changed to VERSION all over the kconfig
scripts. Makefile.kconfig exports this variable so it can be
used by config scripts with getenv().
Now it prints the ppsi version with the present commit, like
diplayed from
	git describe --always --dirty

This also removes an unsed function, that I found because it used
timer_delay().

We don't want "timer_delay(howlong)" because people won't know the
unit while looking at the header.

Also, this removes an unused prototype and adds void when void is due
in timer code.
