toolchain: arc-2016.03: fix generation of dynamic relocs for -pie

Browse Source 
Currently even if -pie flag is provided to LD dynamic relocations
won't be created. That in its turn will break U-Boot self-relocation
functionality.

This fix resolves mentioned problem.

Note as of today this is a sort of off-the-tree patch right from
our binutils guy but in coming day similar fix will be applied to
upstream binutils as well.
