Folks,


I've just updated mxe, then executed

  make build-requirements
  make qt
  make freetype
  make clean-pkg

However, this doesn't remove old stuff from mxe's `usr' subdirectory.
For example, I see

  git/mxe/usr/i686-pc-linux-gnu/share/aclocal-1.13/
  git/mxe/usr/i686-pc-linux-gnu/share/aclocal-1.14/

  git/mxe/usr/i686-pc-linux-gnu/share/cmake-2.8/
  git/mxe/usr/i686-pc-linux-gnu/share/cmake-3.0/

  git/mxe/usr/i686-pc-linux-gnu/lib/libgettextsrc-0.19.2.so
  git/mxe/usr/i686-pc-linux-gnu/lib/libgettextsrc-0.19.3.so

etc., etc., resulting in almost 500MByte more data on my hard disk.

How can I get rid of the no longer needed files after such an update?
