Instead of doing things this way, with a bunch of independent 'if's, I
would suggest computing TARGET in configure.ac and then AC_SUBSTing
it.

IMSNHO, it is bogus to have a separate 'SunOS' target.  This sort of
thing is better handled by feature tests.  I didn't look at the uses
of this, though... on occasion there's no alternative to a platform
test.

The way to set TARGET is by looking at what AC_CANONICAL_TARGET
defined, eg:

    case "$target_os" in)
      linux*)
        TARGET=Posix
        ;;
    ...
    esac
    AC_SUBST(TARGET)
