	Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
    make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
    make: Entering directory '/home/.../package/gluon-status-page'
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    [...]
While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.
After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.
