Under BSD/OS 4.3.1, ncurses doesn't build libncurses++.so* files. It does
build and install other lib*.so* files.

The work/ncurses-5.3/lib/libncurses++.la file has:

# The name that we can dlopen(3).
dlname=''

# Names of this library.
library_names=''


I am not sure why dlname and library_names are empty, but libmenu.la,
libpanel.la, libform.la, and libncurses.la are fine (and there .so files
install fine).

I also noticed that bsdi was not represented in configure script, so
CC_SHARED_OPTS and MK_SHARED_LIB were unknown, but I patched that so they
were set, but it still didn't seem to make any change.

Any ideas on what I should look at?

I have been comparing the build logs from good Linux and bad BSD/OS, but
don't seem to see where the problem is. I can provide these logs.
