committed: Fix NetBSD problem PR80600

[Krister Walfridsson]

I have committed the attached patch to make NetBSD handle -lgcc correctly
for shared libraries.

gcc/ChangeLog:

        PR target/80600
        * config/netbsd.h (NETBSD_LIBGCC_SPEC): Always add -lgcc.

libgcc/ChangeLog:

        PR target/80600
        * config.host (*-*-netbsd*): Add t-slibgcc-libgcc to tmake_file.
