Fabio Porcedda 46bf8e8fd2 cmake: don't use any header available in $(HOST_DIR)/usr/include
The -I<dir> options added to CMAKE_C_FLAGS are passed to the compiler
before the -I<dir> options of the cmake internal headers, so when the
host-xz package was already built, a #include <lzma.h> directive loads
the host-xz header instead of the cmake internal one.

Because we don't want to use any header avaiable in -I$(HOST_DIR)/usr/include,
just get rid of the -I<dir> options in the HOST_CFLAGS.

Fix build failure:
  make host-xz host-cmake

[Thomas:
 - simplify the sed expression. Instead of trying to remove '-I
   <something>' from $(HOST_CFLAGS), simply remove $(HOST_CPPFLAGS)
   from $(HOST_CFLAGS).
 - add the same logic for HOST_CXXFLAGS.]
