openssh unix dev - Apr 2017 - Solaris and use of /usr/ucb

Hi Everyone,

The portability team may be interesting in this. It looks like
/usr/ucb is being used a fair amount on Solaris:

    $ /usr/gnu/bin/grep -IR '/usr/ucb' * | wc -l
        17

According to
https://blogs.oracle.com/partnertech/entry/preparing_for_the_upcoming_removal,
/usr/ucb is going away. I think the mostly equivalent place to find
utilities is /usr/gnu (its present on Solaris 11):

    $ ls /usr/gnu/bin/
    [                eqn              mkfifo           soelim
    addr2line        expand           mknod            sort
    amd64            expr             mktemp           split
    ...

It appears /usr/gnu is not being used at the moment:

    $ /usr/gnu/bin/grep -IR '/usr/gnu' * | wc -l
        0

I don't think it's anything to be concerned about.  The bulk are in the
automatically generated configure script and for the most part it's just
one more place to look.

$ grep -rc /usr/ucb * | grep -v :0
configure:12
configure.ac:3
regress/test-exec.sh:2

Of the remaining ones, 2 in configure.ac are not even for Solaris and the
other one is only a path addition

if test -z "$MANTYPE"; then
        TestPath="/usr/bin${PATH_SEPARATOR}/usr/ucb"
        AC_PATH_PROGS([NROFF], [nroff awf], [/bin/false], [$TestPath])
        if ${NROFF} -mdoc ${srcdir}/ssh.1 >/dev/null 2>&1; then

test-exec also looks innocuous:

if [ -x /usr/ucb/whoami ]; then
        USER=`/usr/ucb/whoami`
elif whoami >/dev/null 2>&1; then
        USER=`whoami`
