Subject: [PATCH] base: Don't produce .gnu.hash tables for Genode.

Genode linker does not support .gnu.hash tables so they will never be
used. Tell the linker not to bother producing them. This should reduce
the size of Genode ELF files a tiny bit without loosing anything
important in the process.

Fixes #4423
