cmake: forward HOST_{C, LD}FLAGS as cmake flags

During the CMake bootstrap phase, the {C,LD}FLAGS set in the bootstrap
environment are not forwarded/converted as CMake flags.

The CMake build contains a bootstrap phase building a minimal CMake
program using a standard Makfile, then reconfigures itself with this
minimal program.

On system with no ncurses installed, and because the prefix option
points to $(HOST_DIR)/usr, if host-cmake was built after host-ncurses,
then ncurses libraries and headers are correctly found (in the host
tree) during the second configuration (because of the prefix). However,
it fails at building ccmake (the curses interface) because the
CMAKE_C_FLAGS, CMAKE_CXX_FLAGS and CMAKE_EXE_LINKER_FLAGS do not
point to the host tree.

Because these flags are needed when running the bootstrap script,
this patch makes sure the same flags are set when running the second
configuration.

samba4: update to upstream patches

Update the package to use patches that have been applied upstream and
update their status comment accordingly.

f_fsid checks have been fixed via upstream patch that allows the cache
to work properly on the result.

Builtin heimdal tools can be worked around via the --bundled-libraries
option to disable those components (even if they are not libraries it
can be done that way).

qdecoder: autoreconf and fix c99 detection

Fixes http://autobuild.buildroot.net/results/da8/da8ce760cdabeb9d4cda00dcc801817e4b4eb12c/

As we're patching configure.ac we need to autoreconf the package.
After reconf, the c99 check fails, so force it like we do elsewhere.

qemu x86/x86_64: Add kernel IPC support

The alsa utils packages require a kernel with IPC support to run.  The
kernel config for the x86 and x86_64 qemu build includes sound support
using the hda driver but without the IPC support the alsa utils won't work.
This patch adds IPC support to the x86 and x86_64 kernel to allow alsa
utils to run and brings the kernel config inline with kernel configs for
other qemu boards.
