kbuild: export HOSTCXX and HOSTCXXFLAGS

kbuild: fix a typo in scripts/Makefile.host
kbuild: fix a bug of C++ host program handling

The comment lines claim:
  C++ executables compiled from at least one .cc file
  and zero or more .c files

But C++ executables with zero .c file fail in build.

For example, assume Makefile is like this:

  hostprogs-y := foo
  foo-cxxobjs := bar.o

In this case, foo is treated as host-csingle.

kbuild: clean up scripts/Makefile.host

$(dir $(f)) always returns non-empty string.

So, $(if $(dir $(f)),$(dir $(f)) is equivalent to $(dir $(f)).

kbuild: clean-up and bug fix of scripts/Makefile.host

Assume we have a Makefile like this:

  hostprogs-y := foo
  foo-cxxobjs := bar/baz.o
  foo-objs := qux/quux.o

In this case, Kbuild creates bar/ directory,
but fails to create qux/ directory.

This commit re-writes directory creation more simply,
fixing that bug.

kbuild: create directory of .o files from shlib-objs notation

Assume we have a Makefile like this:

  hostprogs-y := foo
  foo-objs := bar.o baz.so
  baz-objs := qux/quux.o

In this case, Kbuild fails to create qux/ directory.

zynq: disable -Wstrict-prototypes option for ps7_init.c

The files ps7_init.c and ps7_init.h are supposed to be generated by
hw projects such as Vivado, PlanAhead and then to be copied into
board/xilinx/zynq directory.

But some prototypes in them cause annoying warning messages:

  CC      spl/board/xilinx/zynq/ps7_init.o
In file included from board/xilinx/zynq/ps7_init.c:50:0:
board/xilinx/zynq/ps7_init.h:137:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]

board/xilinx/zynq/ps7_init.c:12854:6: warning: function declaration isn't a prototype [-Wstrict-prototypes]

The prototypes should be

  int ps7_init(void);
  int ps7_post_config(void);
  int ps7_debug(void);

rather than

  int ps7_init();
  int ps7_post_config();
  int ps7_debug();

We do not want to be bothered because of automatically generated files.
But we cannot touch the external projects for now.
What we can do is to disable -Wstrict-prototypes for ps7_init.c

I am Ccing the current working addresses for some of them.

If you want to get back an Orphan board to Active,
please update your email address.

Please do it only if you still have a real hardware to test on.
