description:
use NETBSD_LINK_SPEC_ELF rather than netbsd_link_spec.

My current guess as to why it makes a difference is that riscv, unlike other
targets, doesn't use the macro SUBTARGET_EXTRA_SPECS for anything meaningful

Fixes linking libgcc_s.so, which is now emitted as a dynamic library, not
a static object (which fails, as it has undefined references)

XXX there might be a better way of doing this
