The NetBSD 9 which I installed earlier this year has an older version of gcc:

gcc (nb3 20190319) 7.4.0

That's not from pkgsrc, since it is /usr/bin/gcc

The set of options isn't new either.  The line of script that sets that
"-Bshareable" value was in ncurses 6.1 (since it dates from December 2017).
It was originally from 1995.

NetBSD 9's ld manpage says this:

       -shared
       -Bshareable
           Create a shared library.  This is currently only supported on ELF,
           XCOFF and SunOS platforms.  On SunOS, the linker will automatically
           create a shared library if the -e option is not used and there are
           undefined symbols in the link.

If pkgsrc doesn't support that, it looks like a bug in pkgsrc.
