This update of ppsi submodule does not introduce any functional upgrade,
but some more space is saved in the final executable.

Actually, only compile dependencies are being satisfied, and most of the
functional stuff is stubbed.

This two files where just copied from ptp-noposix
script/Lindent was run on them.
To be checked whether ptpd_netif.h was used by compilation for gnu-linux
(switch).

ppsi was modified in order to use hw drivers provided by wrpc-sw.
ptp-noposix needed some modification too, since some relevant code
(e.g. softpll) is now part of ptp-noposix project (and should become a common
lib in the future).

The rule for "git submodule update" was wrong, so the command was
always performed.  This is a pain if you are using commits in the
submodule that are not yet committed in the supermodule. This always
happens during development.

I'm sorry for the inconvienence, and I thank Aurelio for noting this.

We are always pretty near to the end of RAM, so now that we
have a reserved stack area, we can also check if it overlows.
When it happens, let's print a message forever, so a user who
comes and see what's up will see it eventually.

Pretty often it happens that during trials we pick wrong external
functions (e.g., "printf") and the final link claims horribly about
dozens of undefined symbols.  By having an intermediate wrc.o we can
easily check which are the symbols we really leave undefined for libc
and libgcc to fill, before they resolve them by asking for something
else.
