[PATCH] Use generic NetBSD LINK_SPEC for NetBSD SPARC targets

[Jason R Thorpe]

It turns out that, by an accident of history, LINK_SPEC was wrong
on sparc-netbsdelf and sparc64-netbsd all this time, but we got
lucky for most uses.  "oops."  I'll cook up a patch for the 3.1
branch shortly.

Committed to trunk.

        * config/sparc/netbsd-elf.h (LINK_ARCH32_SPEC): Only specify
        linker emulation.
        (LINK_ARCH64_SPEC): Likewise.
        (LINK_SPEC, NETBSD_ENTRY_POINT): Define.
        (SUBTARGET_EXTRA_SPECS): Add netbsd_link_spec and netbsd_entry_point.
