Unfortunately it seems some versions of Debian/Ubuntu use mawk instead
of gawk by default, and mawk pretends to be POSIX compatible, but at least
versions <= 1.3.3 didn't support POSIX character classes.
We don't really need the various UTF-8 fancy blanks, and even this very
own script already uses sub(/^[ \t]*/, "", arg3); elsewhere, so this
patch just replaces [[:blank:]] with [ \t].

Tested on x86_64-linux (though, Fedora with gawk), ok for trunk?

        * gen-pass-instances.awk: Use [ \t] instead of [[:blank:]]
        for compatibility with mawk <= 1.3.3.
