[Buildroot] [git commit branch/next] qt: make $(HOST_DIR)/usr/mkspecs a symlink to $(STAGING_DIR)/usr/mkspecs

commit: http://git.buildroot.net/buildroot/commit/?id=755a51f327d7d18f31e6b352cdd7032d2d01e35f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

In fact, not only qt can install stuff in $(STAGING_DIR)/usr/mkspecs,
but also libraries that wish to integrate with qmake, such as
qwt. However, qmake and al. will look inside $(HOST_DIR)/usr/mkspecs,
so the easiest solution is to have a symbolic link between the two
directories, instead of copying things around.
