Make install in gtkdiskfree-1.9.3/po causes violations of the sandbox.  The problem is that the installdir variables aren't preceded by $(DESTDIR), and make install tries to install directly to /usr/share/locale, which violates the sandbox.

Reproducible: Always
Steps to Reproduce:
1.emerge gtkdiskfree

Actual Results:  
Here's the relevant output from make install:

Making install in po

else \
  /bin/sh ../mkinstalldirs /usr/share; \
