linuxptp now pulls in the time-sync.target, which other services can
use to make sure they have a valid time before starting.
phc2sys (linuxptp-system-clock.service) starts after ptp4l
(linuxptp.service) so we have a valid time before writing it to the
hardware clock.

linuxptp missing.h header implements a replacement clock_nanosleep()
function, which was used when the thread implementation was not NPTL,
because uClibc failed to provide clock_nanosleep() in such
configurations.
However, uClibc-ng has fixed this problem upstream, and has backported
this change in Buildroot in patch
package/uclibc/0002-librt-declare-clock_nanosleep-independent-of-thread-.patch
(the code is upstream and will be part of uClibc-ng 1.0.31). Due to
this, there is now a conflicting definition of clock_nanosleep()
between the C library and the linuxptp missing.h code, which manifests
itself by the following build failure:
missing.h:117:19: error: static declaration of 'clock_nanosleep' follows non-static declaration
static inline int clock_nanosleep(clockid_t clock_id, int flags,
^~~~~~~~~~~~~~~
In file included from clockadj.h:24:0,
from clockadj.c:24:
This commit fixes that by adding a patch that removes the replacement
clock_nanosleep() implementation from the linuxptp code base.

Since there is quite some duplication in the variables to be passed in
the make environment and as make options between the build and install
steps, this commit introduces LINUXPTP_MAKE_ENV and LINUXPTP_MAKE_OPTS
to avoid the duplication.

incdefs.sh try to define some flags with user_flags() and kernel_flags()
functions. The later is looking at the kernel headers installed on the host
when KBUILD_OUTPUT is not set. If no kernel headers are installed on the host,
the grep fail and HAVE_ONESTEP_SYNC is not set on the command line:
see: grep: /usr/include/linux/net_tstamp.h: No such file or directory
So the missing.h define HWTSTAMP_TX_ONESTEP_SYNC which is also present in the
kernel headers installed in STAGING_DIR (toolchain w/ headers >= 3.2).
Indeed KBUILD_OUTPUT is empty because it's reset in the makefile, so move
KBUILD_OUTPUT in the enviroment while calling "make"/
Also set KBUILD_OUTPUT to STAGING_DIR to find net_tstamp.h.
While at it, use the same arguments for BUILD_CMDS and
INSTALL_TARGET_CMDS.

Add the Linux PTP Project package.
http://linuxptp.sourceforge.net/
The SysV and systemd init scripts start the daemon in slave-only mode on eth0
and synchronize the system clock to PTP.
