bug#28893: [bug-gnu-emacs] emacs-26.0.90 minor build issue on OpenIndiana

[Nelson H. F. Beebe]

I found that the build of emacs-26.0.90 on OpenIndiana (a descendant
of the short-lived OpenSolaris from Sun/Oracle) that is identified as

        % cat /etc/release
                     OpenIndiana Development oi_151.1.9 X86 (powered by illumos)
                Copyright 2011 Oracle and/or its affiliates. All rights

                                   Assembled 17 January 2014

failed at link time because of a missing symbol, tparm.

The configure output shows

        checking for library containing tputs... -ltermcap

and the generated src/Makefile has

        LIBS_TERMCAP=-ltermcap

The problem is that -lcurses, -ltermcap, and -ltermlib on this system
are NOT complete substitutes of each other.

However, that is wrong, because of these contents:

        % nm -D -p /usr/lib/libcurses.so.1 | egrep 'tputs|tparm'
        0000117616 T tparm
        0000116848 T tparm_p0
        0000116976 T tparm_p1
        0000117104 T tparm_p2
        0000117232 T tparm_p3
        0000117360 T tparm_p4
        0000117488 T tparm_p7
        0000121348 T tputs

        % nm -D -p  /usr/lib/libtermcap.so.1 | egrep 'tputs|tparm'
        0000000000 T tputs

        % nm -D -p /usr/lib/libtermlib.so.1 | egrep 'tputs|tparm'
        0000117616 T tparm
        0000116848 T tparm_p0
        0000116976 T tparm_p1
        0000117104 T tparm_p2
        0000117232 T tparm_p3
        0000117360 T tparm_p4
        0000117488 T tparm_p7

I restarted the build with

        gmake LIBZ='-ltermlib -lz'

and it completed normally, and has been successfully installed.
