This is needed for ctypes.util.find_library().  FWIW, on Linux, not
only binutils is used, but also gcc.

Until 3.7, the uuid stdlib module loads libuuid via ctypes, hence the
dependency.  In 3.7, there is a compiled binding, and so the -devel
dependency was dropped.  Also, pkgconf will soon be providing and
replacing pkg-config, which will cause the glib2.0 dependency to be
dropped.
