Let me repeat one fragment from the typescript. After applying my patch
BUILD_DEPENDS and TARGET_BUILD_DEPENDS are set like the following
when USE_CROSS_COMPILE is set to YES.

  - BUILD_DEPENDS contains only build host dependencies
  - TARGET_BUILD_DEPENDS contains target dependencies only (headers).
  - "depends" target doesn't require build host packages (checkperms,
    libtool-base and pkg-config) anymore.

This is exactly what is required by cross-build tools.

I apologize. I really swapped "BH" and "th" by mistake. I'm sorry for that.
