Obscure test failures on DilOS (OpenSolaris-like) with 8.22.157-1b243

[Assaf Gordon]

Hello,

Few tests fail of version 8.22.157-1b243 (and I assume 8.23 now) fail on DilOS 
version 1.3.5.16 .
(DilOS is Illumos kernel (formally OpenSolaris) with Debian-like packaging 
system: http://www.dilos.org/about-dilos ).

The failure is obscure enough so it's probably not worth fixing, just 
documenting.

On this system,
When building with GNU make (/usr/gnu/bin/make), make will use GNU Bash 
(/usr/gnu/bin/sh) - and all goes well.

When building with native make (/usr/bin/make), it will use /bin/sh, which seems a 
form of old AT&T sh:
    $ /bin/sh --version
    version         sh (AT&T Research) 93t+ 2010-03-05

This shell does not support the "local" keyword for variables, and so few tests which 
have shell functions with the "local" keyword fail.

Example (on said system):
    $ /usr/gnu/bin/sh -c 'test() { local i=1 ; echo $i ; } ; test'
    1

    $ /bin/sh -c 'test() { local i=1 ; echo $i ; } ; test'
    /bin/sh[1]: local: not found [No such file or directory]

The following tests fail:
    tests/tail-2/inotify-hash-abuse
    tests/tail-2/F-vs-missing
    tests/tail-2/F-vs-rename
    tests/rm/dangling-symlink
    tests/misc/cat-buf
    tests/misc/stat-birthtime
    tests/misc/stdbuf
    tests/tail-2/wait
    tests/tail-2/retry
    tests/tail-2/symlink
    tests/dd/no-allocate
    tests/dd/reblock
    tests/tail-2/flush-initial
    tests/tail-2/pipe-f2

And the log looks like:
