symbiotic-build: handle CMAKE_INSTALL_LIBDIR for dg
symbiotic-build: handle CMAKE_INSTALL_LIBDIR for dg

Dg was fixed for installing into proper lib paths. Now we have to
properly pass CMAKE_INSTALL_LIBDIR to dg's cmake to handle this
correctly to still have lib as the destination path for libraries even
on 64bit.
