kernel.bbclass: build host programs with native sysroots

Browse Source 
Allow to search header files and libs from native sysroots.

For example, an expanded BUILD_CFLAGS includes:
  '-isystem/builddir/to/linux-yocto/recipe-sysroot-native/usr/include'

And an expanded BUILD_LDFLAGS includes:
  '-L/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib
   -Wl,-rpath-link,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib
   -Wl,-rpath,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib'
