include <unistd.h> to fix build on gcc 4.7

Many of the standard C++ library include files have been edited to no
longer include <unistd.h> to remove namespace pollution in gcc 4.7, so
we need include <unistd.h> manually sometimes.

mklibs (0.1.33+nmu1) UNRELEASED; urgency=low
 * Non-maintainer upload
 * Fix FTBFS with gcc 4.7 due to missing <unistd.h> include (Closes: #667282).

mklibs (0.1.33) unstable; urgency=low
 
  * Adjust the libc_pic directory for multiarch as well.
