* collect2.c (COLLECT_SHARED_INIT_FUNC)
(COLLECT_SHARD_FINI_FUNC): Define default values.
(write_c_file_stat): Use them to call construtor and destructor
functions in shared libraries.
* doc/tm.texi (COLLECT_SHARED_INIT_FUNC)
(COLLECT_SHARD_FINI_FUNC): Document them.
* config/netbsd.h (COLLECT_SHARED_INIT_FUNC)
(COLLECT_SHARD_FINI_FUNC): Define.
* config/netbsd.h (LINK_SPEC): Don't pull in estart if creating a
shared library. Pass -shared through to the linker.
