commit: https://git.buildroot.net/buildroot/commit/?id=23a0f8808ea86612c9b2ce48b65fcf8c0701c04a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.

Thanks to Yann for the live review during the Buildroot summer camp.
